[Platform] SavedObject Management

[rudolf]

Move Saved Object Management into a separate Plugin.

• Allow plugins to configure the values in
  SavedObjectsManagementTypeDefinition for each of their Saved Object types.

  interface SavedObjectsManagementTypeDefinition {
    isImportableAndExportable?: boolean;
    defaultSearchField?: string;
    icon?: string;
    getTitle?: (savedObject: SavedObject) => string;
    getEditUrl?: (savedObject: SavedObject) => string;
    getInAppUrl?: (savedObject: SavedObject) => { path: string; uiCapabilitiesPath: string };
  }

• Move legacy UI to new plugin src/legacy/core_plugins/kibana/public/management/sections/objects
• Move legacy routes to new plugin src/legacy/core_plugins/kibana/server/routes/api/management/saved_objects
• Don't convert deprecated JSON import code to typescript since we will be removing the JSON import UI and routes (src/legacy/core_plugins/kibana/server/routes/api/{import/export}) in 8.0.0 see Remove Dashboard Import/Export API #41439

Progress

• allow to register management section for SO types from NP API: Add SavedObject management section registration in core  #59291
• migrate the object edition view to react: migrate saved objects management edition view to react/typescript/eui #59490
• migrate the server-side part of the management section to NP plugin: Migrate SO management routes to new plugin #59734
• migrate the client-side action registry to NP plugin: Migrate savedObjectManagementActionRegistry to NP plugin #60481
• migrate the rest of the client-side part of the management section to NP plugin: Migrate SO management section to NP #61700

isImportableAndExportable is currently used by the export and import routes, that are going to be moved inside core. This flag needs to be kept inside core, probably in the new SavedObjectType introduced in #56378

[joshdover]

Any good reason not to just migrate all of this info to the new registry in Core? Seems like poor dev UX to have to register info in two separate places about the same thing.

[pgayvallet]

I think the idea was that as the UI part was going to move to it's own plugin, it was making sense to also move the SavedObjectsManagementTypeDefinition to the plugin, and then performing registration using the plugin's API.

However I agree that the dual registration is bothersome (and the isImportableAndExportable is even required in core as it's used by some routes) We could just add a management 'section' in the new SavedObjectsType, and only move the UI to the new plugin.

@rudolf wdyt?

[rudolf]

Yes, I think the primary motivation for a plugin was to move the UI out of core. Partly because there's a lot of legacy that we can only remove in 8.0.0 and also because we might want to make breaking changes in the UI more often than we would otherwise do in Core.

One could argue that most of these configuration options are UI focussed and are closely related to the plugin's public source code such as it's routes:

kibana/src/legacy/core_plugins/data/index.ts

Lines 49 to 54 in 4e8ab56

	getInAppUrl(obj: SavedQuery) {
	return {
	path: `/app/kibana#/discover?_a=(savedQuery:'${encodeURIComponent(obj.id)}')`,
	uiCapabilitiesPath: 'discover.show',
	};
	},

But I think it will make it much less likely to forget if there's only one registration point that has everything.

One could argue that most of these configuration options are UI focussed and are closely related to the plugin's public source code such as it's routes:

Yea, I agree that these config part of the type are (almost exclusively) related to the UI part that is going to be outside of core. But I think the upside of having to perform only one call to register everything that is related to a specific SO type is probably more important.

The client side part is big and still got some issues that may not be solvable atm (I will add more details on the associated PR).

I will split this into 3 separates PRs:

• allowing to register management section for SO types from NP API (this should be the last remaining part to allow plugins to fully get rid of legacy plugin SO registration): Add SavedObject management section registration in core  #59291
• migrate the server-side part of the management section (quite short, only 3 routes)
• migrate the client-side part of the management section (biggest part of the work)

The saved object management UI also still has very hard links to the old clientside (Angular) services, and requires any type of saved object to register a SavedObjectLoader. Since we want to throw away those old client side services completely, we should also make sure the saved object management UI, does no longer require them, but instead just require the registration of a way more slim configuration (since it anyway didn't use most methods/properties in those services).

Working on that atm in #59110. All angular services will be removed. Biggest issue atm is that we don't have a replacement in the NP management plugin for kbnUrl.

kibana/src/legacy/core_plugins/kibana/public/management/sections/objects/_objects.js

Lines 64 to 69 in 56571ba

	goInspectObject={object => {
	if (object.meta.editUrl) {
	kbnUrl.change(object.meta.editUrl);
	$scope.$apply();
	}
	}}

Probably more are not discovered yet, I'm far from done yet.

and requires any type of saved object to register a SavedObjectLoader. Since we want to throw away those old client side services completely, we should also make sure the saved object management UI, does no longer require them,

I'm still using them in #59110, and as migrating the whole UI part is already quite massive work, the initial version is probably still going to rely on them. Removing / replacing them could definitely be a follow-up though.

Just to be sure, it doesn't look like the registered SavedObjectLoaders still relies on angular services, or does they?

kibana/src/legacy/core_plugins/kibana/public/management/saved_object_registry.ts

Lines 52 to 66 in 90cb7a9

	const services = {
	savedObjectsClient: npStart.core.savedObjects.client,
	indexPatterns: npStart.plugins.data.indexPatterns,
	chrome: npStart.core.chrome,
	overlays: npStart.core.overlays,
	};
	savedObjectManagementRegistry.register({
	id: 'savedVisualizations',
	service: createSavedVisLoader({
	...services,
	...{ visualizationTypes: new TypesService().start() },
	}),
	title: 'visualizations',
	});

but instead just require the registration of a way more slim configuration (since it anyway didn't use most methods/properties in those services).

The SO management API is using the loader to (at least) load and save objects during import conflict resolution.

kibana/src/legacy/core_plugins/kibana/public/management/sections/objects/lib/resolve_saved_objects.js

Lines 199 to 201 in 56571ba

	export async function saveObject(obj, overwriteAll) {
	return await obj.save({ confirmOverwrite: !overwriteAll });
	}

What alternative could we be using for that?

@timroes The SavedObjectLoader removal is now a part of #62048
