Move sgabios setup to hypervisor-ironic

This moves setup of sgabios ROM to the ironic hypervisor library.
This is failing to backport to juno because of an error in the sideways ironic
grenade. install_ironic() is expected to setup only python things and happens
earlier than initial package installation.

Copy nova-api-paste.ini if n-api* is enabled

In multi node devstack using multi-host nova-networking, n-api-meta runs
on every machine but n-api only runs on the API node. So copy
nova-api-paste.ini if any version of n-api* is running.
