##### SUMMARY
Move some helper functions from `vmware_host_config_manager` to `PyVmomi`.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
vmware_host_config_manager
vmware

##### ADDITIONAL INFORMATION
`vmware_host_config_manager` has some helper functions (`is_integer`, `is_boolean` and `is_truthy`) to deal with vSphere Web Services API `OptionValue`s. Today, I started to work on issue #61421 and I think these helper functions could be useful there, too. Actually, there are several Managed Object Types with an `OptionValue[]` parameter. Instead of duplicating the code, I think it would be better to move these helper functions to `PyVmomi` in `module_utils/vmware.py`.
