Registration of Elastic Social MBeans

The Elastic Social management MBeans SearchServiceManager, AverageCounterServiceManager and HistogramCounterServiceManager were erronously registered in the MBean server's own default domain (DefaultDomain) and did not expose an application name. They are now named like all other CoreMedia MBeans and expose a type instead of a bean key for the classname.

Object names change from DefaultDomain:bean=SearchServiceManager,tenant=<tenant>

to com.coremedia:type=SearchServiceManager,application=<application>,tenant=<tenant>.

Adjust JMX scripts and monitoring configurations that refer to these MBeans.
