EJBCLIENT-347 added a new 'close' method to the EJBTransportProvider interface. But it has no default implementation, so the implementation in wildfly-http-ejb-client won't compile if that lib's dependency is updated.

AFAICT a no-op default implemenation should be fine as the benefit from EJBCLIENT-347 doesn't apply to the wildfly-http-ejb-client.
