Don't use glossary in rst2man page, sort CLI command list

rst2man doesn't support the `glossary` markup, it's a sphinxism.
Avoid using that and sort the list manually instead.

-  :sorted:
-
-  help [command]
-      Display a list of available commands.
-      If the command is specified, display help for this command.
-  
-  param.set param value
-      Set the parameter specified by param to the specified value.
-      See Run-Time Parameters for a list of parame‐ ters.
-
-  param.show [-l] [param]
-      Display a list if run-time parameters and their values.
-      
-      If the -l option is specified, the list includes a brief
-      explanation of each parameter.
-      
-      If a param is specified, display only the value and explanation
-      for this parameter.
+backend.list
+      Lists the defined backends including health state.
 
-  ping  [timestamp]
-      Ping the Varnish cache process, keeping the connection alive.
+backend.set_health matcher state
+      Sets the health state on a specific backend. This is useful if
+      you want to take a certain backend out of sirculations.
 
-  ban   *field operator argument* [&& field operator argument [...]]
+ban   *field operator argument* [&& field operator argument [...]]
       Immediately invalidate all documents matching the ban
       expression.  See *Ban Expressions* for more documentation and
       examples.
 
-  ban.list
+ban.list
       All requests for objects from the cache are matched against
       items on the ban list.  If an object in the cache is older than
       a matching ban list item, it is considered "banned", and will be
       fetched from the backend instead.
-      
+
       When a ban expression is older than all the objects in the
       cache, it is removed from the list.
-      
+
       ban.list displays the ban list. The output looks something like
-      this (broken into two lines):
-      
-      0x7fea4fcb0580 1303835108.618863   131G   req.http.host ~ 
-      www.myhost.com && req.url ~ /some/url
-      
-      The first field is the address of the ban. 
-      
+      this::
+
+        0x7fea4fcb0580 1303835108.618863   131G   req.url ~ /some/url
+
+      The first field is the address of the ban.
+
       The second is the time of entry into the list, given
       as a high precision timestamp.
-      
+
       The third field describes many objects point to this ban. When
       an object is compared to a ban the object is marked with a
       reference to the newest ban it was tested against. This isn't
       really useful unless you're debugging.
-      
+
       A "G" marks that the ban is "Gone". Meaning it has been marked
       as a duplicate or it is no longer valid. It stays in the list
       for effiency reasons.
-      
+
       Then follows the actual ban it self.
 
-  ban.url regexp
+ban.url regexp
       Immediately invalidate all documents whose URL matches the
       specified regular expression. Please note that the Host part of
       the URL is ignored, so if you have several virtual hosts all of
       them will be banned. Use *ban* to specify a complete ban if you
       need to narrow it down.
