This module can be used to enable or disable Hyperthreading optimization for ESXi host systems in given vCenter infrastructure.
It also checks if Hyperthreading is activated/deactivated and if the host needs to be restarted.
The module informs the user if Hyperthreading is enabled but inactive because the processor is vulnerable to L1 Terminal Fault (L1TF).
