Force saltenv to be a string when passed to state compiler
Load gitfs config values as strings
Load hgfs config values as strings
Load svnfs config values as strings
Don't try to use text_type to force saltenv to be unicode

Fix for #16939

In the case that the master-master has no immediate downstream minions we were just incrementing the syndic_wait N times and then exiting, not pinging the lower level masters/minions. Now, I've consolidate the jinfo_timeout and timeout_at (since they were the same thing) and changed it to add syndic_wait to the timeout_at if you are a master-master, have more time to add, and would have timed out.
Cleanup logging output (to not be confusing)
