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
version under glassfish, which has an easy way of getting a Reply
object, and check its status before returning the results.
The only difference in the method that uses the APIClient is the use of
MultivaluedHashMap.

ColumnFamily

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).

"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

parameter is the last on the path, for example in the ColumnFamily case
