 Review comment:
   The `cloudstack-setup-agent` reconfigures libvirtd config and also adds 
iptables rules for several ports, the post-install script (both rpm+deb) does a 
test if expected iptables rules are in place and adds the ACCEPT rule only if 
needed.
   
   Given not all users may use a config mgmt system such as 
chef/puppet/ansible, running the commands as part of post-install script will 
save the additional work they may need to do themselves (manually or 
automated). @wido I'm okay to advise users via release/admin docs, but I don't 
see any negative/side-effects with the change.

>
> With use of CA framework to secure hosts, the current mechanisms don't secure 
> libvirtd to use those certificates (used by agent to connect to mgmt server). 
> This causes insecure vm migration over tcp instead of tls. The aim is to use 
> the same framework and certificates to secure live VM migration. This could 
> be coupled with securing of a host and renewal/provisioning of certificates 
> to host.
