Related issue: #1155
Description
This PR resolves #1155 by defining a connection-level transaction isolation level when setting up new MySQL connections. I also moved connection params to a slice that's joined into a string later-on because the giant params string was getting pretty unreadable. I also moved cases of
log.Fatalfwith no tokens tolog.Fatal🧹At this time
REPEATABLE_READis used as the isolation for all connections following a discussion here: #1155script/cibuildreturns with no formatting errors, build errors or unit test errors.
