ConfigurationAdmin issues introduced by the new Karaf runtime

[kaikreuzer]

This is similar to #85.
Nothing to blame Karaf/FelixCM for as it is very likely fulfilling all specs.
Nonetheless, we observe many effects where the new behaviour causes existing functionality to break and if we find a way to make it more compatibly, it would be very valuable.

Some issues to look at:

• https://community.openhab.org/t/oh1-config-not-loading/6249
• Queryable persistence service missing - even when active and functional #84

I am not sure whether this might also only be a combination of CM and DS - for DS, there is also a different behavior, since components require now an immediate="true" to be started.

There does not seem to be any general issue - most observations were due to a different start behavior of DS components.
