introduce cider-start-server command

[behrica]

Split cider-jack-in in two and therefore obtain interactive function cider-start-server,
which starts the nrpel server without trying to connect afterwards

If you're just starting out to hack on CIDER you might find this section of its
manual extremely useful.

To a large extend.
I can start now the nREPL server without bothering with the dependencies.

And then an easy cider connect using host and port I know anyhow (as I fix the port in order to have tunneling working)

Something similar could be reached as well by:
#3519

I think you can also add some keybinding for this in the jack-in keymap and mention in the relevant command menu.

If / when #3563 get decided on and this is merged, we could slightly change the docu again.
Because a user has then basically three options when working with remote hosts, in decreasing order of comfort
and increasing guaranty of success and flexibility.

1. Rely on cider-jack-in and its configurations to heuristically do the correct thing for start and connect
2. cider-nrepl-start-server followed by cider-connect with some heuristic to detect server and tunnel ports
3. Manual start of nREPL , ev. manual port tunneling, and cider-connect

Thanks!
