Improve Gitlab Integration

Every time an issue is updated in Aha, the user must remember to click on Actions and send the update to Gitlab. This manual step is different than making all other edits in Aha that automatically save and makes it easy for things to become unsynchronized. I suggest that once and issue has been submitted to Gitlab, any subsequent edits should propagate automatically.

Features created in Aha and sent to Gitlab issues can be modified and saved in Gitlab, but the changes do not show up in Aha. There is some kind of reminder pop up that alerts the user of a discrepancy, but the only option seems to be to manually diff the two records and manually fix it in Aha. Ideally things could change in either tool and update the other, but a compromise might be to create the Gitlab issues so that only the labels can be modified to propagate status back to Aha.
