"The API is currently not supporting notification, but the repair
command that perform via the nodetool relays on the notification to know
when the command terminate.
This series adds support for the repair notification, based on a timer
and periodically check if a current repair command was terminated."
This patch adds a notification support for the repair in StorageService.
When a repair command starts a timer is set to check the status of the
repair, when the repair complets it sends notification for the
successful or fail of the repair.
Because jconsole doesn't run method with variable number of parameters
an additional MBean method was added for async repair with only a
keyspace as its parameter.
All the forceAsycRepair methods are mapped to the asyncRepair metod that
replaces them in 2.2, when options will be supported in the repair, it
will be added to the jmx.
After this patch it is possible to register in the jconsole for
notification, perform a forceAsyncRepair and get the notification that
the repair complets
Sometimes a post command need to return, this adds a method to perform a
post command that returns an int value.
The general postGetVal, can be used for other types if needed.

This patch replace the Histogram data and statistic calculation from the
JMX proxy to the API.
This way the count, sum, min, max variance and square sum are calculated
always on the server.
When an update is perform, the API would return the statistic with a
sample of the last n elements as a sample.
This implementation insure that the counters are correct. The
implementation also allows to set the minimal update interval.
