Generate passwords if they're not specified

[psturc]

https://issues.jboss.org/browse/AEROGEAR-2350

Based on https://github.com/aerogearcatalog/unifiedpush-apb/pull/10 (will rebase after it's merged)

Verification:

1. Clone this branch, build & push this APB
2. Provision without specifying UPS db password & UPS db root password
   • provisioning pod should finish without error
3. Provision with specifying UPS db password & UPS db root password
   • after it's provisioned, check UPS & MySQL DC environment variables - it should contain your values in MYSQL_PASSWORD & MYSQL_ROOT_PASSWORD variables

@psturc awesome - can you rebase and I will test ?

Changing variable names in apb.yml should work.
