Defer Cassandra Startup until we activate a plan that requires FTI

[nsoft]

The current paradigm starts up Cassandra before doing anything. This is slow and should be unnecessary for plans that just want to feed everything they find blindly. It would also be necessary for us to run with a logging config not referencing a JesterJAppender, so that will complicate things somewhat.

Also this Cassandra free mode could be a mode that is supportable on windows.
