Title:
  http:Fix Host header in proxied https connections

Status in apt package in Ubuntu:
  Fix Released
Status in apt source package in Bionic:
  In Progress
Status in apt source package in Disco:
  In Progress

Bug description:
  [Impact]

  Currently CONNECT requests use the name of the proxy as Host value,
  instead of the origin server's name.

  According to RFC 2616 "The Host field value MUST represent the naming
  authority of the origin server or gateway given by the original URL."

  The current implementation causes problems with some proxy vendors. This
  commit[0] fixes this.

  [0] - https://salsa.debian.org/apt-
  
team/apt/commit/86d4d98060f36c7e71c34af20a1193a75496ef72#54d3193c5d10a0032c80c3a6d3f069507265547f

  [Test Case]

  Here's one reproducer an impacted user brought to my attention:

  # /etc/environment 
  http_proxy="http://internal:8080"; 
  https_proxy="http://interal:8080"; 

  To support application development activities in-house, I had to
  configure Azure CLI APT repository following the instructions from
  "https://docs.microsoft.com/en-us/cli/azure/install-azure-cli-apt?view
  =azure-cli-latest":

  $ sudo apt-get update 
  $ sudo apt-get install curl apt-transport-https lsb-release gnupg 
  $ curl -sL https://packages.microsoft.com/keys/microsoft.asc | \ 
  $ gpg --dearmor | \ 
  $ sudo tee /etc/apt/trusted.gpg.d/microsoft.asc.gpg > /dev/null 
  $ AZ_REPO=$(lsb_release -cs) 
  $ echo "deb [arch=amd64] https://packages.microsoft.com/repos/azure-cli/ $ $ 
AZ_REPO main" | \ 
  $ sudo tee /etc/apt/sources.list.d/azure-cli.list 
  $ sudo apt update 

  In the final "apt update" command, APT respects system-wide network
  proxy variables and successfully fetched Canonical repository data
  over HTTP.

  However, it was unable to fetch the newly added Microsoft packages
  repository served via HTTPS.

  By using Wireshark to examine the HTTPS request made by APT, the
  request body reveals as:

  CONNECT packages.microsoft.com:443 HTTP/1.1\r\n 
  Host: internal:8080\r\n 
  User-Agent: Debian APT-HTTP/1.3 (1.6.11)\r\n 
  ... 
  ... 

  
  [Regression Potential]

  * Fix already in debian, and Eoan
  * Has been reviewed/approved by juliank
  * A test package (pre-sru) has been provided to an impacted user, and he 
confirms it solves the situation.
