Remove un-used endpoint for embeddable Insights
What does this MR do?
This reverts !35535 (merged) (and some of !35963 (merged)) as suggested by @jeremy in gitlab-com/Product#1711 (comment 445286171).
A few months ago there was interest in enhancing the Insights feature to allow for these custom charts to be embedded in other contexts. As a first step toward that, an endpoint was introduced for these embeddable charts. However, it has been decided we have higher-priority features to pursue. So this removes that endpoint code, although we intend to pursue embeddable charts in the future so we will likely restore some or all of this code.
