The REST API should provide a way to change the key for a user password.

Describe the solution you'd like
The change should only requires:

• The old password
• The new password

The change password functionality has to implement all the validations needed on the old and new password. If any validation fails the change must fail as well.
The change should be permitted only to the the user that owns the password credential entry.
