5.0.0 policy-handler - new PDP API or old PDP API4.0.0-ONAPdublin

- in R4 Dublin the policy-engine introduced a totally new API
- policy-handler now has a startup option to either use the new PDP API
  or the old PDP API that was created-updated before the end of 2018
- see README.md and README_pdp_api_v0.md for instructions on how to
  setup the policy-handler running either with the new PDP API
  or the old (pdp_api_v0) PDP API
- this is a massive refactoring that changed almost all the source files,
  but kept the old logic when using the old (pdp_api_v0) PDP API
- all the code related to PDP API version is split into two subfolders
  = pdp_api/ contains the new PDP API source code
  = pdp_api_v0/ contains the old (2018) PDP API source code
  = pdp_client.py imports from either pdp_api or pdp_api_v0
  = the rest of the code is only affected when it needs to branch
    the logic
- logging to policy_handler.log now shows the path of the source file to
  allow tracing which PDP API is actually used
- when the new PDP API is used, the policy-update flow is disabled
  = passive mode of operation
  = no web-socket
  = no periodic catch_up
  = no policy-filters
  = reduced web-API - only a single /policy_latest endpoint is available
    /policies_latest returns 404
    /catch_up request is accepted, but ignored
- on new PDP API: http /policy_latest returns the new data from the
  new PDP API with the following fields added by the policy-handler
  to keep other policy related parts intact in R4
  (see pdp_api/policy_utils.py)
  = "policyName" = policy_id + "." + "policyVersion" + ".xml"
  = "policyVersion" = str("metadata"."policy-version")
  = "config" - is the renamed "properties" from the new PDP API response
- unit tests are split into two subfolders as well
  = main/ for the new PDP API testing
  = pdp_api_v0/ for the old (2018) PDP API
- removed the following line from the license text of changed files
  ECOMP is a trademark and service mark of AT&T Intellectual Property.

- the new PDP API is expected to be extended and redesigned in R5 El Alto
- on retiring the old PDP API - the intention is to be able to remove
  the pdp_api_v0/ subfolder and minimal related cleanup of the code
  that imports that as well as the cleanup of the config.py, etc.
