[one-users] incorrect example in documentation

[Rolandas Naujikas]

Hi,

In 
http://docs.opennebula.org/4.8/advanced_administration/application_insight/onegate_usage.html#onegate-usage
the example is incorrect:

curl -X "PUT" $ONEGATE_ENDPOINT

should be

curl -X "PUT" $ONEGATE_ENDPOINT/vm

Regards,
Rolandas
