Support GeoLogCursor in omnibus

As part of https://gitlab.com/gitlab-org/gitlab-ee/merge_requests/1988, we are adding a separate process that will run on the Geo secondary.

We should start add support for this in omnibus for 9.4.

/cc: @brodock

So this is another daemon that we need to support? Can you point me to a discussion where I can check what other options have been considered?

Yes, the main issue is in https://gitlab.com/gitlab-org/gitlab-ee/issues/2467.

There wasn't a lot of discussion about not having a separate process for this because:

• This is a long-running process that polls the database.
• The alternative is to run it in Sidekiq, but this will just sit in Sidekiq and run continuously.
• In the future, we may want to optimize this to a Go executable so that it can be lightweight and fast.

We're open to discussing alternative ideas.
