add support for vscode-server

[andrewmustea]

• Each of vscode's remote development extensions will create and use a
  vscode-server directory in a user's home folder each time a host is
  connected to.
• Unfortunately, the SSH extension is the only extension that has a
  setting that can change the location of vscode-server. Both the
  container extension and the WSL extension are missing the option of
  changing their vscode-server directories.
• Even so, the SSH extension only allows you to define paths for
  individual hosts. It doesn't allow for a default path for all ssh
  connections.
• To edit the host paths, you either need to change your remote SSH
  settings in the vscode application itself, or edit your vscode user
  settings json file.
