Include a migration path for moving legacy users to a stronger hash

* Includes a method for hashing the sha1 passwords with bcrypt to
  increase their security
* bcrypt_sha1 will upgrade to standard bcrypt as per usual with
  passlib
* Provides a script that migrates 20 users at a time to bcrypt_sha1
