Upgrade the Migration Canister to Commit fc79106
__Proposer__: martin.raszyk at dfinity.org
__Source code__: [fc79106bd7662b690ccfce113ce66008fb17eb0a][new-commit]
[new-commit]: https://github.com/dfinity/ic/tree/fc79106bd7662b690ccfce113ce66008fb17eb0a
Features & Fixes
The migration canister now supports subnet deletion during ongoing canister migration (the outcome is as if the canister migration completed before subnet deletion) and exports a metric storing the lifetime of the oldest ongoing canister migration request.
Note. The commit message for fc79106bd7 is stale: that commit does not introduce a new endpoint for listing requests.
