Reset is not implemented for this connection

[Cédric Jeanneret]

Hello there,

There's a really ugly warning when the deploy tries to create the admin user on the overcloud nodes:

While it appears to retry and eventually succeed, it might be good to push something that will handle more gracefully this issue?

More a cosmetic thing than a real bug.
