public final class ConnectionProviders
extends ExtensionProvider<ConnectionProviderInfo>
This is a little different from other hooks in that there isn't any
need to access the hook directly. All access to connection context
providers will be via RescatContextRegistry.
When RescatContextRegistry is initialized, it calls getInstance()
which effectively "wakes up" the hook & initiates registration of
any loaded connection context providers. Providers loaded when
other extensions are subsequently loaded, will be registered real-time.
