Subject: [PATCH 1/5] Feature: daemons: Convert pacemakerd to formatted output.
The main purpose of this is to finish getting pacemakerd moved off the
existing command line handling code (pcmk__cli_help in particular) so
that code can eventually be deprecated or removed. pacemakerd itself
does fairly little printing.

Subject: [PATCH 3/5] Low: daemons: Conditionally enable logging in pacemakerd.
If we're doing an interactive command-line call, use
pcmk__cli_init_logging. At the moment, all command line calls except
for --shutdown do their work before logging would even come up, so we
really only need to do this for --shutdown.
If we're doing a daemon call, use crm_log_init.
