4.2.0 - added the policy-update handling

* API version 4.1.0 - added /policy, /swagger-ui
* new: policy update with queuing of execute-operations
* more data on info - branch+commit-datetime
* expecting consul ip to be in /etc/hosts
* added swagger-ui and added policy to *API.yaml
* common logging - more audits and metrics records
   - directly in promise_request
