Add transport field to EndpointConfig struct

Browse source 
The EndpointConfig struct in the notifications package has some config
fields for a notification endpoint. This commit adds the ability to pass
in an *http.Transport to use when notifying that endpoint of an event.
This is especially useful for endpoints that use self-signed CAs.
