Update pom.xml to reference hapi-fhir 6.3.6-SNAPSHOT. This hapi-fhir release contains a fix for POSTing an XML resource with comments results in a fhir_comments error (#465)

* Update pom.xml to reference hapi-fhir 6.3.4-SNAPSHOT.  This also involves renaming websocket dependencies whose names have changed since 6.2.2 (ex websocket-api to websocket-jetty-api).

* Update pom to reference logback 1.2.10 explicitly to resolve the missing StaticLoggerBinder errors.

* Fix logback issue by pulling the same logback version as hapi-fhir and setting the following system property at boot: org.springframework.boot.logging.LoggingSystem=none.   Also, fix the hapi-fhir-jpaserver-base dependency error by setting this in application.yaml: allow-bean-definition-overriding: true

* Set allow-bean-definition-overriding: true on test application.yaml as well.

* Remove lines in ExampleServerR4BIT that causes an implementation guide version error.

* Upgrade to 6.3.6-SNAPSHOT and once again disable allow-bean-definition-overriding.  Also remove the Bean for IMdmLinkDoa from StartJpaConfig and the Bean for ITermCodeSystemStorageSvc in FhirServerConfigDstu2.

* Explicitly use logback 1.2.10 for both logback-classic and logback-core to resolve StaticBinderLogger not found errors.  Also, remove explici logger disabling code in Application.java.

* Restore Application.java as well as both application.yaml files to the same as master.
