Notify admins 15 days prior to license expiration

Overriding notification methods from Gitlab::License so that admins
are notified only 15 days prior to license expiration.  Previously,
admins were notified 1 month prior to expiration when the
Gitlab::License method was used, but this is inconsistent when
customers are able renew.  Notifying admins early lead to confusion.
