Problem Statement:
- There are undecodable keys in storage that need to be cleaned up.

Significance:
- The undecodable keys were not migrated correctly during a runtime upgrade in 2019, causing issues.
- The removal of these keys ensures a clean and efficient storage system.

Proposed Solution:
- Remove the undecodable Locks and inactive SessionKeys from storage.

Expected Outcomes:
- No undecodable keys will remain on Kusama.
- Only Locks from the faulty 2019 runtime upgrade will be removed.
- No active validator session keys will be removed.
