Bug 29924: Add password expiration feature

This patch adds the ability to define password_expiry_days for a patron
category.

When defined a patron's password will expire after X days and they will
be required to reset their password. If OPAC resets are enabled for the
catgeory they may do so on their own, otherwise they will need to
contact the library

To test:
 1 - Apply patch, updatedatabase
 2 - Set 'Password expiration' for a patron category
     Home-> Administration-> Patron categories-> Edit
 3 - Create a new patron in this category with a userid/password set,
     and an email
 4 - Confirm their password_expiration_date field is set
     SELECT password_expiration_date FROM borrowers WHERE borrowernumber=51;
 5 - Create a new patron, do not set a password
 6 - Confirm their password_expiration_date field is NULL
 7 - Update the patron with an expiration to be expired
     UPDATE borrowers SET password_expiration_date='2022-01-01' WHERE borrowernumber=51;
 8 - Give the borrower catalogue permission
 9 - Attempt to log in to Straff interface
10 - Confirm you are signed out and notified that password must be
     reset
11 - Attempt to sign in to OPAC
12 - Confirm you are signed out and notified password must be reset
13 - Enable password reset for the patron's category and perform a
     password reset
     Note: you will have to find the link in the message_queue unless
     you have emails setup on your test environment
     SELECT * FROM message_queue WHERE borrowernumber=51;
14 - Confirm that you can now sign in and password_expiration_date field
     is set 10 days in the future
15 - Expire the patron's password again
16 - Change the patron's password via the staff interface
