What I did

Refactored cfgmgr Makefile
Why I did it

To avoid code duplication of common libs
How I verified it

Build swss

What I did
The port-channel key migrator was introduced in version 2_0_2 so the expected database version of the test case should be 2_0_2.
It was modified to 2_0_3 when the new version was introduced by mistake. This won't fail the test but disable the require its database version to be updated every time a new version is introduced. (Refer sonic-net#1566 and sonic-net#1614 for details)
This is to correct it by changing it back to 2_0_2.
