Enhancement: handle the case that no buffer change in the latest database version
Current, the following two versions are the same:
- The latest version changed by mellanox_buffer_migrator
- The latest version in CONFIG_DB

That won't be true if another part in CONFIG_DB is updated. In that case, the latest version in CONFIG_DB will be greater than the latest version in mellanox_buffer_migrator.
However, this can break the buffer migrator unit test:
- The db_migrator will always migrate the database to the latest version
- The config database version check will fail in case the latest version in the config database doesn't match that defined in the buffer migrator.

This is to support this case.

…rator test cases as well (sonic-net#1614)

- What I did
Originally, the method advance_version_for_expected_database was introduced (in sonic-net#1566) to handle the case the latest version in CONFIG_DB is greater than the latest version in mellanox_buffer_migrator.
Now there are other database migrators whose test cases can also encounter this situation, like port auto-negotiation (sonic-net#1568) and port-channel for LACP key (sonic-net#1473).
So I would like to make the method public, available for all database migrators.
Related database migrator test cases have been updated accordingly.

- How to verify it
Run the unit test.

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.
