Mathias Fredriksson 4c18034260 fix: Prevent autobuild executor from slowing down API requests (#3726)
With just a few workspaces, the autobuild executor can slow down API
requests every time it runs. This is because we started a long running
transaction and checked all eligible (for autostart) workspaces inside
that transaction. PostgreSQL doesn't know if we're modifying rows and as
such is locking the tables for read operations.

This commit changes the behavior so each workspace is checked in its own
transaction reducing the time the table/rows needs to stay locked.

For now concurrency has been arbitrarily limited to 10 workspaces at a
time, this could be made configurable or adjusted as the need arises.
