50 - Deprecate the KV_STORE feature flag

[justinpark]

This proposal is to deprecate the KV_STORE feature flag and its related assets such as the API endpoint and keyvalue table. The main dependency of this feature is the SHARE_QUERIES_VIA_KV_STORE feature flag which allows sharing SQL Lab queries without the necessity of saving the query. Our intention is to use the permalink feature to implement this use case before 5.0 and that's why we are deprecating the feature flag now.

Is this supposed to be on the 5.0 board?

This was completed in 4.0. Closing.

This card was only about deprecating the feature flag. The task to actually remove the KV Store is here. @justinpark if you want to reference a 5.0 issue, you can just use its link. You don't need to convert the task to an issue. I updated you PR to reference the correct card 😉
