4.2.0 policy-handler - periodic reconfigure

- reconfigure == periodically retrieve the policy-handler config
  from consul-kv and compare to previous config and subconfigs.
  If changed, reconfigure the subunits
- selectively change one or any settings for the following
  = catch_up timer interval
  = reconfigure timer interval
  = deployment-handler url and params (thread-safe)
  = policy-engine url and params (thread-safe)
  = web-socket url to policy-engine (through a callback)
- each subunit has its own Settings that keep track of changes
- try-catch and metrics around discovery - consul API
- hidden the secrets from logs
- froze the web-socket version to 0.49.0 because 0.50.0
  and 0.51.0 are broken - looking around for stable alternatives
- fixed-adapted the callbacks passed to the web-socket lib
  that changed its API in 0.49.0 and later
- log the stack on the exception occurring in the web-socket lib
- unit test refactoring
