Collection mode Poll is not supported

[RavilN]

Currently only Subscribe mode is working.
If Poll mode is selected, anyway it does not collect data by calling Read request, uses subscription and monitored items instead.
Observed in version 0.2.2 and prior.

[RavilN]

In the current version, 2.2.2 polling is available additionally to the subscription/monitored items mechanism.
To enable polling, in the OPC UA Server settings, the Edit Advanced Options dialog, set option readValuesInterval to non 0 value, in seconds.
Column Collection Mode is removed from the GUI.
