Mark Goddard f618a2c4b8 Update seed VM image to CentOS 8.2
If using a CentOS 8.2 bifrost_deploy image on a CentOS 8.1 seed host, we
may see an error such as the following:

    TASK [Ensure the overcloud host image has bogus name server entries removed]
    fatal: [seed]: FAILED!

Running virt-customize with more debug in the Bifrost container, we see
this output:

qemu-kvm: error: failed to set MSR 0x48e to 0xfff9fffe04006172
qemu-kvm: /builddir/build/BUILD/qemu-4.2.0/target/i386/kvm.c:2695: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.

This appears to be an incompatibility between qemu/libvirt in CentOS 8.1
and 8.2.

This change fixes the issue for new deployments by updating the seed VM
image to CentOS 8.2.  Existing deployments will need to update packages
on the seed host to match the bifrost_deploy container.
