2.2.0 policy-handler - customization per company

- 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
