fix(iosxr_ping): Fix IOS XR ping dependency when specifying VRF

[horiagunica]

SUMMARY

This issues Fixes #545 .

When specifying a VRF - there isn't any ipv4 or ipv6 argument from the AFI and if this is specified - the command errors out.

Within the PR I have added another condition that if the vrf argument is given a value - then it will omit the afi value from being placed into the command - that should fix the issue while still maintaing the default (non-vrf) behaviour.

As a side note - I think it might be safe taking this AFI out completely.

@roverflow @Ruchip16 - would you kindly have some time to look at this PR ? Another option is to remove the afi completely - as the commands for IPv4 and IPv6 would work natively anyway (with and without a VRF).

hey @horiagunica thanks for raising the PR, i do not understand the need of adding afi here as commands for ip address works irrespectively of vrf right, we dont need the dependency in the very first place to be added to the module.

@Ruchip16 - try executing that task against any IOS XR device - it's going to throw an error each time. It's currently running ping vrf <input_vrf> <input_afi> <input_destination> - when using a VRF there is no AFI (ipv4/ipv6) within the command in the device OS level.

That's I thought of placing the condition there so if you DO specify the VRF instance - you omit the ipv4/ipv6 (default being ipv4) from the ping command.
