cli: disable smt via cpu_options (#2291)

Browse source 
Disabling SMT dynamically inside the image creates problems on AWS.
The problem should be fixed by disabling smt through the VMM.
By recommendation from AWS: add idle=poll.
This should improve our launch success rate while they investigate some
upstream issues.
