Ricardo Carrillo Cruz 6622b05326 Fix memory ios facts (#21696) 
In order to populate the total and free mem of an IOS device, we run
the 'show memory statistics' command.
The output shows something similar to:

                Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
Processor    BEAE880   335215488    64044364   271171124   268918092   268463852
      I/O    8DAE880    51380224    41880736     9499488     9461552     9352252

We need to just parse the line containing 'Processor' and get the first and third
number for total and free mem, instaed for first and second as the code wrongly
does.

short_description: Collect facts from remote devices running IOS
description:
- Collects a base set of device facts from a remote device that
is running IOS. This module prepends all of the
base network fact keys with C(ansible_net_<fact>). The facts
module will always collect a base set of facts from the device
and can enable or disable collection of additional facts.
options:
gather_subset:
description:
- When supplied, this argument will restrict the facts collected
to a given subset. Possible values for this argument include
all, hardware, config, and interfaces. Can specify a list of
values to include a larger subset. Values can also be used
with an initial C(M(!)) to specify that a specific subset should
not be collected.
