Bug 1013684 Generate unique admin password and show it to the user
Save unique password to file instead of environment variable

Creating an environment variable to the user's home is a bad
pattern because it doesn't propagate between scalable gears.
To workaround this issue we create a password file and read its
content from the autoconfig.php
