Migration end at any block

[ghost-not-in-the-shell]

Explain your changes: This PR modifies the berkeley_migration app so that it only migrate up to the fork block (instead of migrating all the canonical blocks). And it would mark the blocks after the fork block to be pending so that it's convenient for the berkeley_migration_verifier app to only focus on the canonical blocks up to the fork point

Explain how you tested your changes: I've tested this with umt data

berkeley branch is EOF and we don't need berkeley migration at this point
