Request: Allow the user to mount SQL files as a volume

[pippinmole]

Instead of requiring users to build an image containing the migration files, why not allow users to mount a volume containing the migration scripts, so one image build can be used for multiple people's projects?

Nothing overly elaborate or anything, just that wasn't the intended purpose of this particular repo. It was created with the intention of producing the application image and migration image in lockstep with one another. The desire was to reduce orchestration and changes between multiple runs of an app and migration at the same version.

Simply to say, I haven't provided it because I'm not trying to support that usecase.
