Subject: Plugin.py: Add configurable metadata settings to bcfg2.conf (ticket
 #680)

The default settings for ConfigFile metadata were previously hardcoded
in Plugin.py. This change enables setting global user-specified defaults
in the [mdata] section of bcfg2.conf.

Signed-off-by: Sol Jerome <solj@ices.utexas.edu>
