e0dea0c27e EstimatedHistogram: Support empty histogram
When creating an estimated histogram from buckets it is a valid option
to get a zero size array as the buckets array.

In that case the newOffsets method would get a negative value for its
size, which should result in a zero length array of offsets.

5362b2045d APIClient: Support Empty histogram
An empty histogram can return a valid response from the API but without
any buckets.
This is a valid scenario and common for counters of features that are
not supported yet.
In those cases, the APIClient should return a zero length array.

9f9dc88643 FailureDetector: Change getAllEndpointStates implementation
This patch change getAllEndpointStates implementation. The proxy now

and create the result string.

649922fed8 Updating the http client and support API exception
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.

The following MBean implementation where changed

ColumnFamily
CompactionManager
Gossiper
EndpointSnitchInfo
CacheService
StorageProxy

f05c6709dd Fix "nodetool repair" error
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).

54fe3d7ccf ColumnFamilyMetrics: Use schedule for the column family timer
The logic of that timer, should be that after some defined time from the
previous request a new one will be sent, the actuall rate is
meaningless and only cause delyed request to be sent in a higher
frequency after the delayed reponse was returned.
