retest this please

@stcheng, cfgorch in common? I thought it should be in swss repo.

[stcheng]

@lguohan @JipanYanga I agree that this part shall be in the swss repository.

@lguohan @stcheng intfconfd, vlanconfd and possibly other configDB swss daemons may use cfgorch class too. I'm ok to move cfgorch to swss repository, in that case I'll remove the google unit test script for it.

[lguohan]

let's also keep the test in the swss repo.

Moving cfgOrch and keeping the google unit test might be a little challenging and will take more time, googletest framework is created in swss-common.
