vmware_cbt_tool.py: pyVmomi 8.x compatibility

-In pyVmomi 8.0 the SmartConnectNoSSL() method was removed.
 This change uses SmartConnect with the disableSslCertValidation=True
 parameter instead. As it was added in pyVmomi 7.0.2 this is now the
 minimum required version, this was added to the documentation.
 backport of #da94e4df3
