enable ironic inspector

[msherman64]

for ironic-inspector to work with neutron, the following need to be set:

enabled_inspect_interfaces must contain inspector
each node must have its inspect interface set to inspector by
running openstack baremetal node set --reset-inspect-interface --inspect-interface inspector

OR, if default_inspect_interface is set to inspector, new nodes will have their interface
set to this automatically, as well as when --reset-inspect-interface is called.

Finally, inspection_network MUST be set, or ironic will return a cryptic error message about how
"driver IPMI does not support managed inspection".

Before this can be merged, we need to be a little careful about what goes in node_custom_config.

Ironic-inspector supports a "standalone mode" that runs without neutron or glance, so it complains if pxe images aren't present in its own directory. I'd rather not stick 500mb of binary into the site config if we can avoid it, so this is still a work in progress ;)

Can you be more specific about what settings in node_custom_config might be problematic?

Fixed the issues in this commit to kolla-ansible ChameleonCloud/kolla-ansible@6917bd6

Basically in the "standalone mode", ironic-inspector wants the ironic agent kernel+ramdisk in node_custom_config, but I was able to add a flag to skip this
