Rewire SwitchConnectionProvider configuration
Eliminate use of blueprint by replacing it with two components:
OSGiFactorySwitchConnectionConfiguration populates default configuration
into the datastore if not already present.
OSGiSwitchConnectionProviders listens on datastore configuration and
instantiates SwitchConnectionProviders based on observed configuration.
