Added iostype details in network ios_facts module

[lucabrasi83]

SUMMARY

As part of Cisco network devices inventory, we need to be able to differentiate between IOS vs IOS-XE devices. IOS-XE devices (ASR, ISR 4000, CSR1000V) run IOSd and have a very similar CLI as IOS devices https://en.wikipedia.org/wiki/Cisco_IOS_XE.

The current ios_facts module uses the CLI 'show version' command to gather Cisco IOS details. Since IOS-XE devices run a Linux kernel, we can capture the following output 'X86_64_LINUX_IOSD-UNIVERSALK9-M' from the same command to determine whether it is an IOS-XE device. If not, we return IOS as the iostype.
