--------------------------------------------------------

Integrated to master after addressing checkstyle nits.

The above QA run stopped at hbase-rest module which should not have been caused by the patch.

Thanks for the contribution, Vandana.

Thanks for detailed review, Enis.

Will watch for trunk build before integrating to branch-1

> This task involves creating an observer which provides basic quota support to namespaces in terms of (1) number of tables and (2) number of regions. The quota support can be enabled by setting:
> <property>
>     <name>hbase.coprocessor.region.classes</name>
>     <value>org.apache.hadoop.hbase.namespace.NamespaceController</value>
> </property>
> <property>
>     <name>hbase.coprocessor.master.classes</name>
>     <value>org.apache.hadoop.hbase.namespace.NamespaceController</value>
> </property>
> in the hbase-site.xml.
> To add quotas to namespace, while creating namespace properties need to be added.
> Examples:
> 1. namespace_create 'ns1', {'hbase.namespace.quota.maxregion'=>'10'}
> 2. 1. namespace_create 'ns2', {'hbase.namespace.quota.maxtables'=>'2'}, {'hbase.namespace.quota.maxregion'=>'5'}
> The quotas can be modified/added to namespace at any point of time.
