Adds the ability to use the local filesystem when doing reviews by passing the `--imply-local` flag to the reviewer. This functionality is disabled by default. If users make changes to their filesystem (the files are "dirty") the default reviewer (hashes not files) will be use. This is a MINOR release.
This MR adds the ability to add or remove labels to a merge request. These labels are visible in the summary panel and are colored the same way as they would be in the Gitlab UI.
This is a MINOR release.
