Subject: [PATCH] createColumnFamilyGauge to support double values return from
 the API

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.

This fix (scylla-jmx)
Fixes #12
