Metadata and other improvements:

* Added support for Client tag in groups.xml
* Added support for nested Group tags in groups.xml
* Added support for negated groups in groups.xml
* Added DatabaseBacked plugin mixin to easily allow plugins to connect
  to a database specified in global database settings in bcfg2.conf
* Added DBMetadata plugin that uses relational DB to store client
  records instead of writing to clients.xml
