Introduce ConnectionDetails interface

Add a `ConnectionDetails` tagging interface which will be used
to mark beans that are a source of configuration settings for
connection to a remove service. When such beans are available,
they will take precedence over any connection-related
configuration properties. Configuration properties that are not
related to the connection itself, such as properties that control
the size and behavior of a connection pool, will still used.
