MEDIUM: config: remove the "process" keyword on "bind" lines

Browse Source 
It was deprecated, marked for removal in 2.7 and was already emitting a
warning, let's get rid of it. Note that we've kept the keyword detection
to suggest to use "thread" instead.

process <process-set>[/<thread-set>]
This restricts the list of threads on which this listener is allowed to run.
It does not enforce any of them but eliminates those which do not match. Note
that only process number 1 is permitted. If a thread set is specified, it
limits the threads allowed to process incoming connections for this listener.
For the unlikely case where several ranges are needed, this directive may be
repeated. <process-set> and <thread-set> must use the format
all | odd | even | number[-[number]]
Ranges can be partially defined. The higher bound can be omitted. In such a
case, it is replaced by the corresponding maximum value. The main purpose is
to have multiple bind lines sharing the same IP:port but not the same thread
in a listener, so that the system can distribute the incoming connections
into multiple queues, bypassing haproxy's internal queue load balancing.
Currently Linux 3.9 and above is known for supporting this.
This directive is deprecated in favor of the more suited "thread" directive
below, and will be removed in 2.7.
