Exit when printing error about database config

berrange · berrange · commit 2d7c346f0c8c · 2015-01-22T15:11:18.000Z
When finding no configured database, devstack prints
a suitable error in the logs

   "No database enabled"

but then just carries on running, as a result the developer
is very unlikely to ever see the original error message.
Change the 'echo' to a 'die' so that it stop immediately
making the error message clearly visible.
