[rfe] TripleO CI must collect and publish console logs from fake overcloud nodes during introspection and deployment

[Dmitry Tantsur]

Without seeing what is happening on a node it may be impossible to understand what does not work. See https://bugs.launchpad.net/tripleo/+bug/1770972 for a good example. It may be as easy as running 'nova console-log <ovb node>' during introspection/deployment, but there may be caveats with credentials, etc. Still, it's an absolute requirement for the CI debugability.

So ovb bmc uses pyghmi:

Looks like pyghmi supports SOL (Serial over Lan), but by default there is no iohandler[1].

Could we create an iohandler in OVB BMC that creates a remote serial console[2] in Openstack Nova?
Then the CI jobs could do:
ipmitool -I lanplus -U admin -P password -H 127.0.0.1 sol acticvate and redirect the output to a file?

(tripleo-ci bug triage)

This is a great idea, and the suggestion from harald-jensas sounds like a nice way to work around the serious security implications of injecting nodepool creds.

As this is a feature we would like, but don't presently have in our CI tooling, marking as RFE to indicate that this is (needed) net-new functionality.

We already collect console logs.
