[FLINK-3355] [rocksdb backend] Allow passing options to the RocksDB backend
This introduces an `OptionsFactory` to lazily create RocksDB Options and
uses those to initialize the
RocksDB instance.
Tests: The necessary flag `setCreateIfMissing(true)` is defined on the
options as part of the lazy creation of the RocksDB options. That way, it
doubles as a test that the options are actually passed to the
`AbstractRocksDBState`.
At the moment, this does not persist the options factory with the
checkpoint, but uses upon restore the same factory that is defined on the state
backend. We have to check if that may cause issues with safepoints.
Note: This also cleans up the generics in the RocksDB state classes.
