Implement Cassandra Configuration Groups

Implement configuration groups for Cassandra 2.1.

The configuration template was taken from a
default installation of Cassandra.
A few changes have been made (and documented in the template)
to disable snapshot-related features.
Trove currently does not provide any support for guestagent-local
snapshots.
They may be used internally and/or removed by backup implementations.
The operator would be also required to have remote access to the
filesystem - a feature currently not supported by Trove.

Changes have also been made to default authenticator/authorizer
which are necessary to enable user functions.

An effort has been made to make most settings configurable.
Exceptions include the above mentioned and RPC/filesystem -related
properties - options that may, when misconfigured,
easily render the instance inaccessible by Trove.

Notes on Cassandra configuration file:

Cassandra uses a YAML configuration file.
Changes made to this file are applied after node restart.
