HE: Filter IP addresses based on 'ipv6_deployment'

[tinez]

At the beginning of HE deployment we set the 'ipv6_deployment' fact based on host's address. This var should be the source of truth for whether to use an IPv4 or IPv6 address for the HE VM.

Until now we were simply picking up the first address that was reported by 'virsh' and using this throughout the rest of the process.

This PR adds filtering of the reported addresses based on the value of 'ipv6_deployment'. Additionally we're picking the first address to make other usages of 'local_vm_ip' nicer.

it seems it's broken on el8stream too now

it seems to me that due to the now-functional ipv4 dhcp entry the vm boots with default route on ipv4, which breaks the assumption and route manipulation of he setup

Same problem happens for IPv4-only deployment. Somehow the bootstrap VM enables and gets IPv6 now
