Mgmt reorg -- submodule and build rules for sonic-mgmt-common (#4765)

- Why I did it
New repo sonic-mgmt-common is introduced for the common translib related code. This commit adds build rules for this new repo.

- How I did it

Added sonic-mgmt-common submodule
Added build rules for the new sonic-mgmt-common repo. It creates two deb packages -- sonic-mgmt-common_1.0.0_{arch}.deb and sonic-mgmt-common-codegen_1.0.0_{arch}.deb. Package cache is enabled.
Added dependency on sonic-mgmt-common for mgmt-framework and telemetry debs and dockers.
- How to verify it
Full build and incremental builds
Basic ACL and interface opreations through REST, KLISH CLI and gNMI

- Description for the changelog
Git submodule and build rules for the new sonic-mgmt-common repo.
