Slack vitess r12.0.5 vtctld cherrypicks

[tanjinx]

Description

These are cherrypicks needed in vtctld for vtadmin UI to work, similarly as what we did in v11 upgrade through PR
tinyspeck#247.

However, the majority changes in tinyspeck#247 are already in v12, so in this PR, just backport those are not in v12.

The branch slack-vitess-r12.0.5-vtctld is based on the v12 release branch slack-vitess-r12.0.5, and slack-vitess-r12.0.5-vtctld will be used for deployment.

For reference:

This will serve as the base branch for 11.x vtctld branches, and should not be merged into master.

I compiled a list of cherry picks you see below from the following PRs:

https://github.com/tinyspeck/vitess/pull/231
https://github.com/tinyspeck/vitess/pull/232
https://github.com/tinyspeck/vitess/pull/233
as PER: https://paper.dropbox.com/doc/Deploys--BiBeEroaHSASXm33RaJsy5GMAg-4DTMhk7UnGtetj5tqzJ75#:h2=But-where-do-the-cherry-picks-

and started to apply them to this branch using:

git cherry-pick -m1 {pr-merge-sha}
all cherry picks with [x] are done, the rest still need to be applied manually. It's a very tedious process due to many (and I mean MANY conflicts that need to be resolved manually). There are also a number of proto conflicts on generated files which I attempted to fix as follows:

make install_protoc-gen-go
make proto
