Similar to @munnerz work in #205 we need a way to specify a CassandraCluster version.
This will allow Navigator controller to figure out which version specific operations must be performed during a cluster upgrade.
It'll also allow a user to omit the Cassandra image and tag if they're just using the semver tagged images from Docker registry....the default since #222
