Add -only-up create command option to skip down migration creation
migrate create -only-up … would help those who use only up migrations instead of up/down pairs.
What's the motivation for this? Empty migrations are ignored. See: https://github.com/golang-migrate/migrate/blob/master/MIGRATIONS.md
New create command flag fills the gap for only up project users.
Only up projects are full-fledged citizens in migrate. They are supported because users can create and use only up migrations while never migrating down. This behaviour is also indirectly documented as deleting down files permitted in some cases.
Common workflow for only up project is to create and commit up files and skip all down files completely (there is no reason to keep many empty files in file tree or vcs).
We are encouraging users to use migrate create command but at the same time we are forcing only up project users to delete down files manually or by wrapping migrate create with the side script.
With the -only-up flag migrate will be as safe as it is and more friendly to the only up projects.
@dhui are you interested in merging?
I'll fix tests to meet maligned error then.
