http: send connection: close when closing conn

Browse Source 
HTTP/1.1 mandates connections which do not support keep-alive and
close the connection send the connection: close header, see
https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.10

This page also provides more information:
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Connection

I understand that HTTP/1.1 defaults to keep-alive - and that the
Connection: close header is required when closing a connection.

This adds the Connection: close header in the 400 and 414
responses sent on client errors.
