"This series adds latency related depricated methods to the storage
proxy.
The implmenetation mimic origin, in which the depricated methods calls
the counters that replaces them."
In LatencyMetrics the URL is passed without the ending slash, this
patch use the same notation in ClientRequestMetrics.

This uses the recent estimated histogram and the API based estimated
histogram to support the sstable per read recent and total estimated
histogram.

This adds the depricated total and recent estimated histogram.
It uses the new RecentEstimatedHistogram for the recent value and the
API based estimated histogram for the total latency.

The EstimatedHistogramWrapper is a helper class that holds the API
related data, so that a class that uses an EstimatedHistogram can
replace it with the wrapper and keep most of its code as is.

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.

This adds the StorageMetrics, the implementation is based on the API.
The API definition are in storage_service under the metrics part.
After this patch, it will be possible to connect with jconsole and see
the StorageMetrics mbean.

This Adds the CommitLogMetrics object.
The implementation is based on the API, that define in commitlog.json
After this patch, it will be possible to connect with jconsole and see
the CommitLogMetrics.

"The column family matrics is a set of data related to the column family.
This series adds an API based on the ColumnFamilyMetrics mbean.
It has a stub implementation, just so the JMX proxy would get a response."
"The CacheMetric is used to return statistics on the cache. This series adds
the definition of the CacheMetric and initilized it in the CacheSerivce.
After this series it will be possible to connect with jconsole and see that
there are 3 mbean available for key, row and counter cache statistics."
The CompactionMetrics is used to report statistics about compaction. It
is based on calling the API that defined in compaction_manager.json

The CacheMetrics holds information per a specific Cache type (key, row
or counter)
It the clas was modified to use the API. The API definition can be found
in cache_service.json under metrics.

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.

The latency metrics holds a single counter, so there is no need to add
the total_latency to the url it is pointed to.
Removing it, can shorten the url in the API definitions.
LatencyMetrics
This import the implementation of CASClientRequestMetrics
ClientRequestMetrics and LatencyMetrics with modification to use the
APIMetrics with a given URL.
The Metrics where added to keep the same naming of of the MBean as they
are in Origin.
