Analytics visualization designer should fail gracefully when cube data fails to load

Followup from: !114533 (comment 1322427885)+

Currently the visualization designer fails silently / not obviously when the CubeJS requests fail to load. If the meta endpoint fails, the metrics panel is completely hidden. If the load endpoint fails when selecting a metric, the preview panel sits in an infinite loading state.

Investigate error catching options from the cubejs-client which is dealing with data fetching, and show an obvious user-facing error when loading fails.

Implementation plan

• in analytics_visualization_designer hook into the cubejs query-builder component queryStatus event to surface errors.
• store error state
• when error exists, display a user facing error via GlAlert: Analytics|An error occurred while loading data.
• when queryStatus fires again initiating another request, clear the error state
• tests
