[Archive Migration testing] Fuzzy testing on small volume of data

[dkijania]

First stage of archive migration testing. Scope of this level is to assure correct behavior on random data which not necessary looks like mainnet. Goal is to quickly test migration process on Pull Request. Test should not be longer than 15 minutes.

Design

1. Create random couple blocks and genesis ledger.
2. Perform migration
3. Pick up some addresses which balances should be verified:
   a) addresses defined in genesis ledger and not accessed later
   b) addresses not defined in genesis ledger but created later
   c) addresses defined in genesis ledger and updated later
