lib: Partial Revert of 4ecc09d and modify zclient connect behavior
Commit 43cc09d has been shown to cause several issues with clients connecting. Partial revert, since I wanted to keep the debug logs added for that commit, as well remove the piece of code that stops attempting to connect to zebra. If we've failed a bunch of times, there is nothing wrong with continuing to do so once every 60 seconds. I've debug guarded the connect failure for those people running bgp without zebra.
