I agree, we have to be careful not to paper over bugs while we try to
overcome typical environmental delays that come w/ booting, rebooting $x
number of random hardware nodes.
To make this a little more crystal clear, I'm trying to determine is where
progressive delays and retries should be injected into the workflow of
deploying an overcloud.
Should we add options in the product itself that allow for $x number of
retries w/ a configurable set of delays for introspection? [2]  Is the
expectation this works the first time everytime?
Are we overstepping what CI should do by implementing [1].

Additionally would it be appropriate to implement [1], while [2] is
developed for the next release and is it OK to use [1] with older releases?

Thanks for your time and responses.
