SetGuestInfo and GetGuestInfo script
Starting from version 5.5 vmware-cmd is not anymore part of ESXI command tools.
Almost any function has been migrated to new tools, like esxcli.
Almost but not all.
The most notable absence is the missing of a replacement for the options seguestinfo and getguestinfo.
Scope of this script is to create a script to fill the gap caused by these missing features.
