bgp: T1875: Add BGP allow range command documentation (#431)

This is a documentation addition for the allow range command
within BGP, as well as the associated limit command as well.
There was a few spelling mistakes that were fixed too, but
not anything big.

This command disables route reflection between route reflector clients.
By default, the clients of a route reflector are not required to be
fully meshed and the routes from a client are reflected to other clients.
However, if the clients are fully meshed, route reflection is not required.

.. cfgcmd:: set protocols bgp <asn> listen range <prefix> peer-group <name>
This command is useful if one desires to loosen the requirement for BGP
to have strictly defined neighbors. Specifically what is allowed is for
the local router to listen to a range of IPv4 or IPv6 addresses defined
by a prefix and to accept BGP open messages. When a TCP connection
(and subsequently a BGP open message) from within this range tries to
connect the local router then the local router will respond and connect
with the parameters that are defined within the peer group. One must define
a peer-group for each range that is listed. If no peer-group is defined
then an error will keep you from committing the configuration.
.. cfgcmd:: set protocols bgp <asn> listen limit <number>
This command goes hand in hand with the listen range command to limit the
amount of BGP neighbors that are allowed to connect to the local router.
The limit range is 1 to 5000.
