There are cases where the API uses double to return a value that the JMX
expect to be long.
For example in mean column row size. This type difference should not be
a problem and the result should be cast to long or int.
This patch allows the values to be double and cast the result to int or
long.

The column family store API was changed so it would have a single API to
return the snapshot size.
This changes the JMX to use the same API regardless if it is called from
the ColumnFamilyMetrics or from ColumnFamilyStore.

histogram to support the sstable per read recent and total estimated
histogram.

This change adds path parameter support, for the cases that the path
parameter is the last on the path, for example in the ColumnFamily case

The getEstimatedRowSizeHistogram is based on the column_family.json that
defined in the API.
The implementation in the MBean and in the metrics is now works with the
get histogram as long array method in the client.

This changes the Timer in ColumnFamilyMetrics, CommitLogMetrics and
LatencyMetrics to be an APITimer.
The APITimer is passed the url to get the data from.

The ColumnFamilyMetrics is used to report statistic of a column family.
This adds an adaptation for the ColumnFamilyMetrics that works with the
API that define in column_family.json
It adds the ColumnFamilyMetrics to the ColumnFamilyStore and expose the
keyspace name, so the ColumnFamilyMetrics would have access to it.
