Integration with solr - New SearchComponent

[akkumar]

• Custom Search Component specific to HBasene.
• Solr configuration - NamedList - to take in the parameters needed by HBaseConfiguration, and the properties manually added to a freshly created 'Configuration'
• For the initial phase, providing the search component to search from an index would be useful, for validating and providing a service against a static, but very large scale data.

We can later revisit integrating the add/delete rest calls of solr with this.
