#248 Allow the application to start when database not available

[Miro Halas]

At this time when an demo web application (or other
application) which is integrating with Open Core
starts, it is not deployed when the database it tries
to connect is not available.

I would like the application to be still able to
deployed even if database is not available and just
user interface would notify administrator or user
what is going on.

Administrator would then be able to either start the
database or for example change the configuration
settings to change what database is the application
to connect.
