there is a new endpoint for the dataset GET method is /api/v1/dataset/<datasource PK(a.k.a datasource id without type>. I added it at here

I actually used GET /v1/dataset endpoint at first, but then changed it to GET /datasource/get/. As far as I know, Explore now supports (or will soon support?) other sources than datasets, such as SQL queries. Tagging @hughhhh for transparency.
Also, the /v1/explore/ endpoint uses DatasourceDAO to get datasource and the response from /v1/dataset endpoint is missing some fields compared to datasource from /v1/explore, which caused some components in Explore to crash

I propose we stick to the legacy /datasource/get endpoint for now and create a new /v1/datasource API in the future and refactor

@kgabryje Thanks for the explanation, we will optimize it in the future.

SUMMARY
Currently when user open Explore, we always send a request to
/v1/exploreendpoint, which assembles Explore initial data - slice, form_data and datasource.When user goes to Explore from Dashboard (by clicking "Edit chart" or char title), most of the data needed to assemble Explore should already be available in Redux store.
This PR implements using data from Dashboard Redux store to initialize Explore without calling
/v1/exploreendpoint.If user opens Explore from Dashboard, check if slice, formData, datasourceId and datasourceType are available. If they are, fetch datasource metadata and hydrate Explore using slice, formData and datasource.
If they are not available, call
/v1/exploreand hydrate Explore.We can't reuse datasource from Dashboard. Datasources metadata on Dashboard is trimmed so that datasource contains only columns and metrics used by charts on that dashboard. In Explore we need to be able to access all columns and metrics, which means we must fetch those from API.
