WIP restapi: Add fields for CPU Overcommit (4/5)
This patch series adds support for CPU Overcommitment based on counting
host threads as cores for the purpose of VM startup/shutdown/migration.
Patch 4: Allow reporting and setting of new fields for overcommitment
from the REST API:
vds_dynamic.cpu_ht_enabled - boolean, host supports hyperthreading
vds_dynamic.vdsm_count_threads_as_cores - boolean, corresponds to
vdsm.conf option report_host_threads_as_cores
vds_groups.count_threads_as_cores - boolean, whether overcommitment
option is enabled by user
