- added try-except for top level Exception into all threads
of policy-handler to avoid losing the thread and tracking
the unexpected crashes
- rediscover the deployment-handler if not found before
and after each catchup
- refactored audit - separated metrics from audit
- added more stats and runtime info to healthcheck
= gc counts and garbage info if any detected
= memory usage - to detect the potential memory leaks
= request_id to all stats
= stats of active requests
- avoid reallocating the whole Queue of policy-updates after catchup
= clear of the internal queue under proper lock

- fixed the bug of unpredictably stopping of the periodic catch-up
step-timer due to thread race condition in policy-handler
= added critical sections under the reentrant lock on every group
of local var change in step-timer
- added more stats for healthcheck to track each type of
job-operation separately
= that helps narrowing down identifying the potential problems
- unit test coverage 76%

- policy-handler uses dns based discovery of
deployment-handler - driven by config
- new data structure for deploy_handler section of config
-- changed from string "deployment_handler" in 2.3.1
to structure in 2.4.0
deploy_handler :
# name of deployment-handler service
# used by policy-handler for logging
target_entity : "deployment_handler"
# url of the deployment-handler service
# for policy-handler to direct the policy-updates to
# - expecting dns to resolve the name
# deployment_handler to ip address
url : "http://deployment_handler:8188"
- logic is backwards compatible with 2.3.1 format
- removed import pip from audit
-- import pip broken in pip 9.0.2 (2018-03-19)
-- import pip conflicts with requests
-- pip API is not officially supported
-- see links for more

- periodically catchup - interval is configurable
= max_skips defines the number of times the catch_up
message that is identical to previous one can be skipped
- do not catchup more often than the interval
even between the manual catchup and auto catchup
- do not send the same catchup message twice in a row
to the deployment-handler but not exceed a hard limit
on catchup max_skips
- catchup if the deployment-handler instance is changed

- added etc_customize/ folder and customize.sh script
= customize.sh script is expected to be overridden by company
to customize Docker image build
= the whole etc_customize/ folder is copied into docker image
= it is up to the company what to put into that folder - any files
- added customize/ folder with CustomizeBase and Customize classes
= CustomizeBase defines the interface and the default=ONAP behavior
= CustomizeBase is owned by ONAP and should not be changed
by the company
= Customize inherits CustomizeBase
= policy-handler instantiates Customize
to get the customized behavior
= Customize is owned by the company and should be changed
by the company = ONAP is not going to change Customize
= the methods of Customize are expected to be overridden
by the company to change the behavior of the policy-handler
= sample Customize class can be found in README.md
= Company is allowed to add more files to customize/ folder
if that is required for better structuring of their code
as soon as it is invoked by the methods of Customize
