move migrations.groovy into canvas-builds

move file migrations.groovy from canvas-lms to
canvas-builds

refs DE-328
flag = none

test plan:
- Ensure build passes
- Ensure migration cache is used when there is no migration
- Ensure the cache is not used with skip cache flag
- Ensure the cache is not used if we force a db
migration
