add config to merge on specific comment

[AbdulAli19]

right now, kodiak merges pr's that match a specific label (default is automerge). it'd be nice if it worked with comments as well.

suggestion

a new config e.g., automerge_comments that takes in a list of strings and kodiak attempts to merge when any of the specified strings are present in a pr comment

This sounds good. The only concern I have is that when adding comments to trigger merges, it may be awkward to cancel that action. This probably isn't an issue since many other projects work off comments.

You could use https://github.com/peter-evans/slash-command-dispatch to trigger a github action which adds the automerge label
