[Workspace] Restrict saved objects finding for non dashboard admin

[wanglam]

Is your feature request related to a problem? Please describe.

This is a feature request. Non dashboard admin user can only view saved objects in permitted workspaces after workspace enabled. The non workspace saved objects can't be listing when out of workspace.

Describe the solution you'd like

We are going to refactor saved objects finding method in the workspace client wrapper. There are mainly three cases in the finding method. We are going to overwrite the finding options according below logic.

1. Without options.workspaces and options.ACLSearchParams, should use permitted workspaces or default ACLSearchParams.
2. With options.workspaces, not permitted workspaces will be filtered out.
3. With options.ACLSearchParams, principals will be replaced to requested user.

Describe alternatives you've considered
