METRON-1570: Downgrade Solr version to match HDP Search
## Contributor Comments
This PR downgrades our Solr version from 6.6.2 to 5.5.4. The purpose of
this change is to catch any incompatibilities with 5.5.4 at compile time rather
than at runtime when using Solr 5.5.4. In theory Solr client code compiled
with 5.5.4 should work with 6.6.2.
All changes were fairly minor. A summary includes:
- disabled Solr auto-configuration in REST
- changed Solr client instantiation to be compatible with 5.5.4
- changed Solr collection listing call to be compatible with 5.5.4
- changed Kerberos configuration to be compatible with 5.5.4
- updated the in-memory SolrComponent to be compatible with 5.5.4
I tested this in full dev with HDP Search 2.2 (Solr 5.5.4) and could not
find any issues. I also enabled Kerberos and everything worked as expected.
