In http-server, support multiple connectors

Currently, it is possible to use multiple servlet with only one connector. Both jetty 8 and 9 support multiple connectors within the same http-server, and then link each servlet to a connector by connector name.

I started working on it. Do you need https support for this?

yes...

And do you think you need more than one connector per servlet mapping? Or is one enough? I.e. would it need to be supported to have 2 ports open for the same logical servlet mapping (open port and secured port)?
