Convert aaa-password-service to OSGi DS
This patch serves as a blueprint of what a replacement for blueprint's
clustered-app-config needs to look like. Since we are replicating
the functionality of config DS -> component, this ends up being more
complicated than we'd want it.
Providing the infrastructure replacement for odl:clustered-config
is part of MDSAL-598. This patch provides one possibility how that would
be realized.
