This changes the CompactionManager getCompactionHistory to use the new
get_compaction_history API.
It uses the CompactionHistoryTabularData to parse and report the
results.
After this patch nodetool compactionhistory would work.

There are cases where the API uses double to return a value that the JMX
expect to be long.
For example in mean column row size. This type difference should not be
a problem and the result should be cast to long or int.

long.

The RecentEstimatedHistogram updates its value from the API with an
array of recent values.
This array can be empty, in that case the getBuckets method should just
return a zero size array.

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

"This series complete the change in the API that replaces the formatted string
functionality with an API that return an array of objects.

as origin has."
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.

follow from highest to lowest:
* command line
* configuration file according to the hirarchy:
