From 2416ab0120bfe15cd3c5ef6cd0bbade288b32e7a Mon Sep 17 00:00:00 2001
From: Kiran Kamineni <kiran.k.kamineni@intel.com>

Subject: Add support for parsing profile yaml files

Add code to parse profile configuration yaml
The parsing function is global and returns a client
which can then be used to get or apply specific parts
of the configuration on top of an extracted helm chart.
P14: Add unit test that covers both ProcessProfileYaml
     and CopyConfigurationOverrides
P15: Adding mock_charts and mock_profiles
     We expect to reuse these files for other unit tests

Issue-ID: ONAPARC-348
Change-Id: I4504d0b158fdfef476b8c2a461d33306926545d7
