Feature request: Logging of what migration ran and when

Currently, the migrations collection only keeps track of the current migration and whether or not control is locked. While this is helpful information, it'd be great if there was an option for the package to insert a document in the collection that stored what migration ran, when it ran, if it was successful, and which direction it was run. It may be something that is disabled by default and enabled with a configuration option.

I forgot to mention, I'm happy to create a pull request for this as well.

That would be great. Our SyncedCron package has a cronHistory collection to do something similar.

I also just thought of something to go along with this: if logging is enabled and a migration fails, since that's being logged, it'd be helpful to log the error message if possible as well. I just ran into an issue where at some point after deploying with mup, migrations locked and I'm having trouble finding it in the mup logs.
