[FAB-10094] Add tests for rebuilding ledger components

This CR adds tests for dropping and rebuling different
ledger components such as statedb, block storage indexes,
and config history db.

This CR also adds test that makes sure that v1.2 can work with and
rebuild components from ledger created by v1.1 code
