Remove deprecated ControlPort commands from GETINFO info/names listing

If GETINFO commands status/version/num-concurring and status/version/num-versioning are used in Nyx or tor-prompt, Tor writes to its log file:

[warn] status/version/num-concurring is deprecated; it no longer gives useful information
[warn] status/version/num-versioning is deprecated; it no longer gives useful information

These commands should be removed from interpreter's /help GETINFO listing. They are deprecated according to [[https://gitweb.torproject.org/torspec.git/tree/control-spec.txt|control-spec.txt]]:

"status/version/num-concurring"
"status/version/num-versioning"
  These options are deprecated; they no longer give useful information.

[0.2.0.30] (more than 10 years):

o Newly deprecated features:

• The status/version/num-versioning and status/version/num-concurring GETINFO controller options are no longer useful in the v3 directory protocol: treat them as deprecated, and warn when they're used.

Probably, there are also other deprecated commands in /help listing. They should be removed too.

P.S. Initially it was reported in [comment]. teor [[http://ea5faa5po25cf7fb.onion/projects/tor/ticket/28676#comment:8|recommended]] to create separate ticket.
