New function to return HOSTIDS hash and bug fix
to handle the case that no custom fields are defined
Bug fixes
* work on older perl where keys() takes a hash and not a hashref :-(
* explicit output in case there are not custom attributes or ESX hosts
* explicit output in case no VMs found
Adjust VM hardware defaults to sane values (for RHEL6)
Bug fix to use proper mime type of application/json instead of text/json
New Feature: Check tool to validate ESX time synchronisation
* Use vCenter credentials and do everything through vCenter
* Check that every ESX server has at least one NTP source defined
* Check the deviation of the system clock
* Check all ESX servers and vCenter server in one go
* Optionally select ESX servers to check via regex (matchhosts=)
* Optionally set allowed time deviation (alloweddeviation=)
* Optimized execution by doing bulk calls to vSphere
