new command `cider-copy-jack-in`

Is your feature request related to a problem? Please describe. Using CIDER on a remote machine would be eased in complex remote scenarious by:

• open a shell in Emacs and "go ito the final remote server"
• generate teh "jack-in-command' and "copy" it
• paste it into remote shell

Describe the solution you'd like A Cider build in commnad such as:

(defun cider-copy-jack-in (params)
  "docstring"
  (interactive "P")
  (let ((params (thread-first params
                  (cider--update-project-dir)
                  (cider--update-jack-in-cmd))))
    (kill-new (plist-get params :jack-in-cmd))))

but full-featured, in case tghis command does not a consider all cases

Describe alternatives you've considered cider-connect and picking a remote host. This does only work for 2simple" ssh connection, but not for "complex" connections (such as multihop, or remote+docker)

some design considerations: should allow for the cljs form, you might also need the cljs startup forms (shadow/select :app , etc)
