Fix the stubbed implementation of forceRepairRangeAsync() which is

passed to "nodetool repair".
forceRepairRangeAsync() works similarly to the existing forceRepairAsync()
just sending the additional start/end tokens as two new options to the
REST API. Unlike the parallel Cassandra code, we don't do any fancy
processing on these tokens to intersect them with the node's token ranges -
we'll do this intersection in the C++ code, where the repair is actually

The API returns errors with an HTTP code 400, 404 or 500 depending on
the cause with a json object that contains the failure reason. The
error message should be populate to the JMX calling client, translated
to the appropriate exception.
This patch adds the ability to detect API failure and throw a runtime
exception with the returned message.
It is up to the calling method what to do with the exception, if it
would do nothing, the calling client would get a RuntimeException,
depends on origin MBean definition, the caller can catch the exception
and throw a specific kind.
Note that any exception that is thrown must be known to the JMX client
or it will not be able to process it.
As a first step, this patch replaces the jersey client to the newer

The existing scylla-jmx code had reversed logic for the success of the repair:
it reported to "nodetool repair" a failure when the repair was successful :-)
Note that "nodetool repair" waits until a FINISHED notification, and then reports
a failure if it previously got any SESSION_FAILED notification; So if repair was
successful, all we need to do is to avoid sending a "SESSION_FAILED" message.
But we don't need to send any additional "SESSION_SUCCESS" message to signal
success. That message type is only used to report progress to the user (a
"session" is part of the repair work, so seeing sessions completing shows
progress), but because Scylla doesn't support this progress report yet, we
can't send these notifications yet, and there's no point in sending one such
message at the end - it's only confusing (especially when the text is the same
as that of the FINISHED message).

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.

After MAX_RETRY (currently set to 30s) the proxy will shutdown.

"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
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.

Some of the depricated function in StorgeProxy uses the Metrics object
to get the information.
This adds an implementation for the following:
getReadOperations
getTotalReadLatencyMicros
getRecentReadLatencyMicros
getTotalReadLatencyHistogramMicros
getRangeOperations
getTotalRangeLatencyMicros
getRecentRangeLatencyMicros
getWriteOperations
getTotalWriteLatencyMicros
getRecentWriteLatencyMicros
It uses the implementation in ClientRequestMetrics without adding new
functionality.

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.

calls to the relevent API that define in column_family.json
This patch also do some clean up, by removing leading underscore from
