Ian Barwick eb2cdf8a98 repmgr: improve handling of command line parameter errors ...

Previously providing a parameter which requires a value (e.g. -f/--config-file)
would result in a misleading error like "Unknown option -f".

Rather than suppress getopt's error messages, we'll rely on these to inform
about missing required values or unknown options (as other PostgreSQL tools
do), though we will still provide our own list of command line errors and
warnings countered above and beyond getopt's sanity checks.
