There was a confusion in the API between key and keyspace.
It was changed in the API so the JMX should be modified accordingly.

With the addition of the configuration file, the scylla-jmx should not
add command line configuration parameters by default. Instead, it should
add those parameters only if they are explicitely given to it.

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.
This patch allows the values to be double and cast the result to int or
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 is a valid scenario and common for counters of features that are

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

SCYLLA_CONF then SCYLLA_HOME then for relative 'conf' directory
