Update Scholarships configuration for deploy

Sean suggested using db1048.eqiad.wmnet instead of db1001.eqiad.wmnet
for the database. Ellie set start/end dates for the 2014 application
cycle. Security review is complete so vhost can be enabled.

This changeset requires new variables in the private repo:
* passwords::mysql::wikimania_scholarships::app_user
* passwords::mysql::wikimania_scholarships::app_password
See Ibbd1bfd for related update in labs.
