Allow to remove the version string in HTTP responses.
Normally Unit responds to HTTP requests by including a header like
Server: Unit/1.30.0
however it can sometimes be beneficial to withhold the version
information and in this case just respond with
Server: Unit
This patch adds a new "settings.http" boolean option called
server_version, which defaults to true, in which case the full version
information is sent. However this can be set to false, e.g
"settings": {
"http": {
"server_version": false
}
},
in which case Unit responds without the version information as the
latter example above shows.
