Add scaffold to test replaying the block of the app (#337)

Adds initial scaffold for tests which enable full execution of the block
by comet-bft utilities:
- `BlockExecutor`

Those are test can be used in various scenarios:
- e2e application test asserting that after certain ordered operations,
we reached expected state
- deterministic execution tests i.e execute some random operations and
replay them and check that app hash matches
- early block execution tests (if we introduce other backends than
memdb)
