Metabase setup status not shown correctly

[mahalakshme]

Issue:

org: shelter, env: staging

• Currently even if creation of reports fails, on refresh of page when it is loading, it shows as 'Setup done'

Tech detail:

• It is because in organisation_config table we are keeping track a variable called, metabaseSetupEnabled whose set value seems to be in contradiction with the success status of Metabase Canned Reports setup which is still under progress.
• Also we are setting the metabase via foreground thread and refresh of the page will not complete the setup, say in case metabase during refresh is only in its second step and collection creation which is 4th step may not get completed.
  ie., /setup-toggle endpoint implementation needs to be made more robust so the status conveyed and shown in the UI is consistent.

AC:

• Status should not show as Done, when it is not Done.
• Refresh of the page or moving to a different page as well should show the status of Metabase setup correctly(ie., either loading or Done or the UI for not triggered)
• Should work in a consistent manner for orgs with large data as well.

Moved back as other Metabase cards are in progress and we want to serialize the code changes to avoid conflicts
