Add log_hint() function for logging hints

Browse Source 
There are a few places where additional hints are written as log
output, usually LOG_NOTICE. Create an explicit function to provide
hints in a standardized manner; by storing the log level of the
previous logger call, we can ensure the hint is only displayed when
the log message itself would be.

Part of an ongoing effort to better control repmgr's logging output.
