Laine Stump ab238e23b4 util: remove check for iptables binary during virFirewallInit 
It's unclear exactly why this check exists; possibly a parallel to a
long-removed check for the firewall-cmd binary (added to viriptables.c
with the initial support for firewalld in commit bf156385a0 in 2012,
and long since removed), or possibly because virFirewallOnceInit() was
intended to be called at daemon startup, and it seemed like a good
idea to just log this error once when trying to determine whether to
use firewalld, or direct iptables commands, and then not waste time
building commands that could never be executed. The odd thing is that
it would sometimes result in logging an error when it couldn't find a
binary that wasn't needed anyway (e.g., if all the rules were iptables
rules, but ebtables and/or ip6tables weren't also installed).

If we just remove this check, then virCommandRun() will end up logging
an error and failing if the needed binary isn't found when we try to
execute it, which seems like it should just as good (or at least good
enough, especially since we eventually want to get rid of iptables
completely).

So let's remove it!

Libvirt API for virtualization

Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.

For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.

Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
