SECFIND-244: Add notifyAndAttachCanister to canisters API

[dskloetd]

Motivation

We want to recover from interrupted canister creation in the frontend code.
To do this we should be able to notify the CMC and attach a canister without first making a transfer, as the transfer has already happened before the process got interrupted.
See this doc for details.

Changes

1. Add notifyAndAttachCanister which can be used to recover canister creation based on an existing ICP transfer.

Tests

1. Added unit tests.
2. Cleaned up the existing test on which the new test was based, by using fake time instead of stubbing out setTimeout and not mocking console.log as nothing gets logged and this just makes debugging harder.
3. Tested manually in a branch with the end-to-end solution.

Todos

• Add entry to changelog (if necessary).
