PR contains some changes from PR #696. Once that PR is merged will rebase this PR.

Most of the codacy issues are in conflict , One of them should be disabled. Ex. D203: 1 blank line required before class docstring D211: No blank lines allowed before class docstring

Do we have separate ticket for covering unittests? @akash2144

@mariyappanp Currently no API is available for testing, Once API is available will write test case there. CORTX-30029

[mariyappanp]

It would be better to maintain rest api framework if we separate it from ha service like ha/framework/restapi. What do you think, @akash2144 @shaileshsvc @ArchanaLimaye
