Fix Ironic service bind IPs

This patch removes the get_input's in the service templates
and instead uses our new bind IP string replacement mechanism
to correctly set the local bind IPs for the Ironic API.

It also avoids using MysqlNetwork to set Ironic my_ip.

This patch adds a new IronicNetwork setting which is used
to control which network Ironic will use for its PXE network
traffic.
