The use of mean and variance as histogram parameter names makes more
sense.
This also make it safe to use an empty histogram that holds no samples.

In origin an undocumented feature (bug?) is that passing null as a host
name for getRack and getDatacenter returns the rack or datacenter
according to the loopbck address.
This follow the same behaviour, so when the host is null, the function
will not fail but will call the API with the local loopback address

"This series addresses two issues:
It uses the column family timer to verify that the API is available. After a
number of retry (currently set to 30s) the JMX proxy will shutdown.
Second, it reduce the number of unimplemented depricated method, following
origin way of calling the counters implementation from the depricated methods."
Some of the depricated method in column family are replaced by counters
in Origin. Still, some tools, like nodetool uses the depricated API.
This adds an implementation to some of the depricated method that is
based on the column family counters similiar to origin.

"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.

"This series modified the Histogram support to get all of its statistic from the
API. By doing that not only the sample will be accurate but also the on going
statistics of count, sum, min, max mean and std.
It also adds a Timer support, Timer are defined in the yammer library and uses
a Histogram that is been updated regularly. The Timer implementation in the
series would use the APITimer that uses the API.
Current code that uses Timer and Histogram was modified to use the updated
implementation with a URL."
