* Add IdleTimeout setting to http.server
Without such a timeout there is a risk of resource leakage from piling up connections, particularly when exposing Traefik to the Internet.
Set the default to be 180 seconds
* Add IdleConnTimeout to Traefik's http.server settings
Without enforcing a timeout Traefik is susceptible to resource leakage, particularly when deployed as a public facing proxy exposed to the Internet.

* Add ability to set authenticated user in request header
Some web applications provide the ability to authorize users based on
the authenticated from Basic Auth. This patch provides a way to set a
key to which the authenticated user can be set in the Header.
For example, if I set `HeaderValue = "X-WebAuth-User"` and authenticate,
my application will be able to read my user name from that header and
provide me with the proper access.
This fixes#802
