'Method returns the ID of VC performance counter by its full name.
A VC performance counter is uniquely identified by the
tuple {\'Group Name\', \'Counter Name\', \'Rollup Type\'}.
It will have an id - counter ID (changes from one VC to another),
which is required to query performance stats from that VC.
This method returns the ID for a counter,
assuming \'CounterFullName\' => \'Group Name:CounterName:RollupType\'.'
