[New] Added feature to ignore a realm on DB init 

This can be very handy to not start the connection pool for realms which
you know won't connect to the DB (but is not transient) - weird isn't
it? =))

The property is: db.ignore.realm.<realmName>

The actual use case is the following:
- You have a realm which use is used normally and is not transient so
you have a configuration for it
- you have another StrolchComponent which opens its own transactions to
the DB but you only require a subset of the realms so you then use the
ignore property to ignore the other realms.
