* Fixed a bug in standalone subscription subscriber: It was adding REQUESTED subscriptions to the active subscription registry. (Only ACTIVE subscriptions should be added.)
* Start work on this
* Work on interceptors
* Attempt fix
* Avoid environment dependency
* Test fixes
* One more test fix
* One more build tweak
* Lots of cleanup
* A bit more cleanup
* Still more cleanup
* Some test fixes
* Add legacy methods temporarily
* Don't auto-scan interceptor beans
* One more test fix
* rsolve merge conflicts
* Address review comments
SearchParamRegistry and SubscriptionRegistry now both poll retrying connection to the server. This will help in particular in the scenario where the subscriptions are managed in a standalone server that depends on a FHIR Server being available to pull search parameters and subscriptions from.
* Reorganizing packages and dependencies to support standalone subscription running within a CDR container where all hapi modules are on the classpath.
Moved Subscription registry out of interceptor and introduced SubscriptionLoader
* Created ActiveSubscription and moved cache bits into it
* Moved ExecutorQueue stuff out into its own class
* Add test and supporting code to validate SubscriptionConstants.EXT_SUBSCRIPTION_RESTHOOK_DELIVER_LATEST_VERSION behaviour
* Added SubscriptionCheckingSubscriber
* Moved a few beans to @ComponentScan
* Replaced use of beanFactory with concrete factory classes
* Switched test to use subscribablechannel
* Added SubscriptionLoaderFhirClientTest
* Confirm that our SubscriptionProviderFhirClient works with a live fhir client
* Register interceptors with DaoConfig instead of RestServer.
Also, Rename @VisibleForTesting methods with ForUnitTest
* Fix triggering service so it uses new subscriptionmatcherinterceptor
* Renamed "Database" classes to "Dao"
* processing -> matching naming change
