  Autodetect spring.jpa.database from spring.datasource.url

provided.

* pr/6579:
  Polish audit event endpoint support
  Improve MBean without backing Endpoint support
  Add MVC and JMX endpoints to retrieve audit events
  Add JMX without backing `Endpoint` support

Closes gh-6579

Improve support for MBeans without a backing endpoint by introducing
a `JmxEndpoint` interface. The `JmxEndpoint` is intentionally
similar in design to the `MvcEndpoint` from the `mvc` package and
allows for completely custom JMX beans that are not backed by any
real actuator `Endpoint`.

The `AuditEventsMBean` has been refactored to use the new interface and
has been renamed to `AuditEventsJmxEndpoint`.

See gh-6579

Add MVC and JMX specific endpoints that allow audit events to be
retrieved.

See gh-6579

Decompose `EndpointMBean` to improve support for JMX endpoints without
a backing `Endpoint`.
