If the comment changed on the server, but the extension still
shows the old version, we'll prevent the extension from overriding
the server's latest version. We'll warn the user that the
comment has changed since they last saw it.

Introduce startEdittingComment and cancelEdittingComment
commands that will open and close the VS Code comment
text area. The cancel command also resets the comment body

different things.

See merge request gitlab-org/gitlab-vscode-extension!185
