Add RegistryLock schema to Flyway deployment folder (#270)

* Add RegistryLock schema to Flyway deployment folder

Added creation script of RegistryLock to Flyway deployment folder.

Fixed previous scripts (PremiumList- and ClaimsList-related) for
FK name change (cause by table name changes: names are quoted now).
We should consider generating foreign key names by ourselves.

Since the alpha database is empty, we dropped and recreated the schema.

Added instructions on how to submit new database incremental changes
in the README file.

Updated RegistryLock.java, removing unnecessary annotations:
- For most fields, the 'name=' property is no longer necessary not that
  the naming strategy is in place. The exceptions are the two used in
  the unique index.
- The @Column annotation is implicit.
