fix(repo): allow users to disable events

[ecrupper]

Adding the --drop-event flag to let the CLI disable webhook events for repos.

Also added a few more aliases and an AlternateDeploy constant ("deploy") because we call the event Deploy in the UI, so it's not very intuitive that it should be supplied as deployment. Made it a constant because the linter was yelling.

nice - good call on the deploy thing. do you think we should do similar for pull?
