Implement case-fetcher/save/refresh to CLI

[captn3m0]

The paradigm of:

1. Fetch some cases
2. Expand theses cases
3. Keep the data updated.

Seems good. You can run (1) multiple times to increase your universe size. (2+3) can be run on a schedule to keep the data enriched. Implement this into the CLI with some thought.

1. The query params that were used to fetch the cases will result in different results, so the universe is shifting.
2. Some support is done, enrichment needs to be moved to CLI
3. One good thing is that if we query the same CNR via different means (act type, case type fir number), even though enrichment might not pick up few items (case type, act type), it will get added to the database wherever available (at fairly cheap at that).
