This commit adds support for per-node overrides to the libvirt chart.
For example, to enable a relaxed ACS check on one host, but not another,
one may have the following in the override values file:
conf:
overrides:
libvirt_libvirt:
hosts:
- name: host1.fqdn
conf:
qemu:
relaxed_acs_check: 1
- name: host2.fqdn
conf:
qemu:
relaxed_acs_check: 0
