Make cas storage an hidden implementation detail of CidStore (#130)v0.1.4-pre6v0.1.4-pre5

- Bumped ZEN_SCHEMA_VERSION
- CasStore no longer a public API, it is hidden behind CidStore
- Moved cas.h from public header folder
- CidStore no longer maps from Cid -> Cas, we store entries in Cas under RawHash
- CasStore now decompresses data to validate content (matching against RawHash)
- CasChunkSet renames to HashKeySet and put in separate header/cpp file
- Disabled "Chunk" command for now as it relied on CAS being exposed as a service
- Changed CAS http service to Cid http server
- Moved "Run" command completely inside ZEN_WITH_EXEC_SERVICES define
- Removed "cas.basic" test
- Uncommented ".exec.basic" test and added return-skip at start of test
- Moved ScrubContext to separate header file
- Renamed CasGC to GcManager
- Cleaned up configuration passing in cas store classes
- Removed CAS stuff from GcContext and clarified naming in class
- Remove migration code

+ * Note that since this does not end up pinning any of the chunks it's only really useful for a small subset of use cases where you know a
+ * chunk exists in the underlying CID store. Thus it's mainly useful for internal use when communicating between Zen store instances
+ *
+ * Using this interface for adding CID chunks makes little sense except for testing purposes as garbage collection may reap anything you add
+ * before anything ever gets to access it
