[HttpListener] This feature has nothing to do with GauloisPipe

[cmarchand]

Starting GauloisPipe as a HttpListener was a request for a project at Francis Lefebvre / Lefebvre-Sarrut.

This feature is an integration feature, and has nothing to do with pipeline processing. If a client need to start a GauloisPipe as a service, then GauloisPipe has to be startable as a service, needs to provide an API to add new files in queue, needs to provide an API to stop, but it must not provide an Http Server.

This feature requires a dependency on jetty:jetty-server, and this library has quite often vulnerabilities. Removing the http service will secure gaulois-pipe, and let each integrator integrate gaulois-pipe as he likes, removing the constraint to use jetty.

As this change introduce a breaking-change, this should be done in a major release.
