RFE: image-based installs, error out if Could not create the host

[pcfe]

with image based installs (branch feat118), when the following happens

INFO:    Deleting VM ID sattestclient02.sattest.pcfe.net [Fri May  1 03:04:29 CEST 2020]
Host deleted.
INFO:    Recreating VM ID sattestclient02.sattest.pcfe.net [Fri May  1 03:04:35 CEST 2020]
Could not create the host:
  Render user data template for sattestclient02.sattest.pcfe.net task failed with the following error: execution expired

then 6000 seconds later

obviously it would be better if such a run would error out when Could not create the host: happens instead of waiting until the timeout (6000 seconds in this example) is reached.
