Implement job-types endpoint support methods for MapR plugin

This change implements the optional methods in the Plugins SPI
to support the job-types endpoint for the MapR plugin.

Config hints at this point are unchanged. Additional work may be
needed to provide config-hints specific to MapR plugin versions.
