XD-153 Gauge module implementation

The code is essentially a copy of the RichGauge implementation
with the simpler Gauge type.

time we create a gauge.
XD-178 - Create default constructor for DefaultContainer
Support -X DELETE Rest Operation

- Undeploy modules
- Stop and remove Redis Adapters between modules
XD-161. RedisChannelRegistry.stopAndRemoveAll is leaving taps in place for now
