Anton Sorokin 09311ae258 [#22] Threat shutdown and exit requests correctly
Problem:
As in [#22], we want to shut down our LSP server correctly.
That means we should close the pipe and end process after an exit request.
This require proper `shutdown : unit -> bool` function passed
to `Jsonrpc2.Make.run` which returns `true` after
the server received an exit request.

Right now both exit and shutdown requests are setting
LSP server's internal var `_quit` to true. It's very intuitive to
use this var in `shutdown`, but we can't do it, since in this case
the server would stop receiving new messages right after the
shutdown request, despite the fact  according to the LSP specification
it had to wait the exit request.

Solution:
Instead of `_quit : bool` use
```
status : [ `Running | `ReceivedShutdown | `ReceivedExit ]
```
and suggest
```
shutdown () = s#get_status = `ReceivedExit
```
in docs for `Jsonrpc2.Make.run` and in the templete/example.
