Trevor McKay 08233d358b Implement job-types endpoint support methods for CDH plugin
This change implements the optional methods in the Plugins SPI
to support the job-types endpoint for the CDH plugin.

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