List migration logs

[sandre1]

• logs for list available (all), pending, applied migrations with applied-date visible
• option --format FILE-FORMAT in CLI to list migrations (as logs) in .edn and .json format

Overall looks good to me, would just swap out cheshire for clojure.data.json

@ieugen thanks for doing a more thorough review, and I'm good to merge if everything looks good to you

@yogthos : I think it's ready to merge.
I am not particularly fond of terminal output with logging.
It would be nice to improve that, but I think the code is an improvement to migratus and a step forward.

Agreed, we could do a separate PR to make that nicer. And just released 1.5.3 to Clojars with the update @sandre1 thanks for spearheading the effort on this. :)
