upgrade: framework for writing software upgrade migration function #703

Closed SebastianElvis closed 2 months ago

Closes #700 Closes #701

This PR provides a framework for defining software upgrade migration function, based on Osmosis' approach.

The PR also provides a unit test that submits a software upgrade gov prop. The gov prop defines a migration function that removes an existing account and inserts a new FP, and the test asserts corresponding state diff before and after the gov prop. This proves that the migration function can manipulate states.

LGTM, can we add in the future an e2e test for this and the fork?

Of course, planned in https://github.com/babylonchain/babylon/issues/698
