[FLINK-4753] [kafka] PeriodicOffsetCommitter should synchronize on
checkpoint lock
The `PeriodicOffsetCommitter` in Kafka 0.8 currently doesn't synchronize on
the checkpoint lock when creating a copy of the partition offsets in the
current state.
This change proposes to pass the checkpoint lock into
`PeriodicOffsetCommitter`, and let `PeriodicOffsetCommitter` use
`Kafka08Fetcher#snapshotCurrentState()` to make copies of the current state.
This PR also includes removal of some leftover unused code after some
recent refactoring of the Kafka connectors in commit 53ed6ada.
