dividing info "large"/"small" partitions (+gossiper). Message bulk
queries in v3 mbean reflects this.

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.

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.

This patch change getAllEndpointStates implementation. The proxy now
gets from the API a list of objects, it creates the endpoint map from it
and create the result string.
After this patch the nodetool gossipinfo should be formatted like
origin.
After this patch the nodetool gossipinfo return:

getRecentTotalTimeouts
This patch adds the impelementation for the depricated method
getRecentTimeoutsPerHost and getRecentTotalTimeouts.
The implementatin is based on origin, the recent version of the method,
return the delta from the last call to the method.

This patch adds the implementation of the dropped messages and the
recent dropped messages.
The MessagingService holds a timer that periodically load the dropped
messages from the API and distribute the results between the
DroppedMessagesMetrics instances.
This mimic the timer behaviour in origin, only it does one API call for
all Verb.

This patch import the DroppedMessageMetrics from origin, as oppose to
origin, it does not run timers but relay on the Messaging sevice.

Sometimes it is required that a meter will not handle its own data, like
the APIMeter does.
This patch break the added functionality of APIMeter into two classes,
APISettableMeter is a Meter with a set value method and APIMeter adds
the functionality that reads from the API.

"This series adds some deprecated methods implemenetation to the CacheService
depnding on its metrics.
It also stub the getDrainProgress in StorageService."
This patch adds the describering method to StorageService, the
implementation is based on the storage_service API that is define in
storage_service.json
The implementation reflect the changes in the API, that returns an
object vs. the jmx_describe ring.

"Scylla's configuration can change the listening address and port of the API,
the jmx proxy need to use this same configuration.
This series adds the ability to add a path to a yaml configuration file and the
jmx proxy would read its configuration from there. Configuration from system
properties/command line is still supported and the configuration hirarchy is as
follow from highest to lowest:
* command line
* configuration file according to the hirarchy:
- command line
- SCYLLA_CONF
- SCYLLA_HOME
- relative conf directory
* default values
The configuration definition was moved to a configuraion class that responsible
for getting the information from the command line and the configuration file."
When calling the API move method, the proxy should pass the new_token
parameter.

This patch adds a configuration object to the jmx proxy that support
both the system/command line based properties and it accept a yaml
configuration file. The later options allows the jmx to read scylla
configuration file and connect to it based on this configuration.
The configuration file reader uses a yaml parser that was added to the
pom.xml
If no configuration file is found in the command line, it would look for
SCYLLA_CONF then SCYLLA_HOME then for relative 'conf' directory
