Review request for atlas and Hemanth Yamijala.


Updated the diff so that the HBase and SOLR packaging are moved to a new embedded_services
profile.  By default the packaging is skipped and the configuration is set of Berkeley and
ElasticSearch.  If the embedded_services profile is used to build the distro then HBase and
Solr are included and Atlas is configured to start and use them.

Bugs: ATLAS-823

Repository: atlas


Use of embedded HBase and SOLR is not preferred due to multiple concerns, including:

1. lack of support by Ambari makes it difficult to handle kerberization, upgrade/migration,
2. not suitable for production use - no HA, local-storage

Atlas should remove support for embedded HBase and SOLR. Instead Atlas should be updated to
use external HBase and SOLR.
