[Feature Request] Support Pending (and past) group participants in NOWEB engine

[gwhitelaw]

A clear and concise description of what the problem is. Ex.

In the WEBJS engine we get a list of active, past and pending participants. The last is very useful for an admin bot. However NOWEB only returns active participants.

A clear and concise description of what you want to happen.

I'm just keeping a list of past participants, but pending is not accessible with NOWEB

A clear and concise description of any alternative solutions or features you've considered.

I believe as WEBJS has this, I do not need more information.
