Removed keyspace creation as this is now done by CassandraDatastore
Travis no longer needs to create Cassandra Keyspace as this is now done by CassandraDatastore
Added keyspace creation test
Initial addition
Added creation of keyspace

- Now creates Cassandra keyspace and its various options defined in
connectionDetails using KeyspaceActionSpecificationFactoryBean
- Renamed constants to remove cassandra prefix as it is redundant
- create* methods now protected as Setup test class no longer has to
create keyspace
- factory beans now destroyed on destroy()
- read method brought in as connectiondetails can have non string values
when a ConfigObject is passed in from Groovy
- added validation of property Enums
