change to use poll field instead of active field

[listerr]

Seems to make more sense to use the (new?) poll field rather than active field in case there are switches active but we don't want IXPM to poll them.

@barryo Any chance we can get this merged please? :)

Hey @ichilton

I can't merge this immediately I'm afraid 😢

I need a chance to look at the original semantics of pollable and why it was added and then examine the consequences of this and #694 for ~150 other IXPs that may take a different meaning of pollable (which the UI hint suggests it's to do with the artisan job only).

Then docs + release notes may all need to be updated.

If you're happy with your updates, can you just use a locally modified version for now?

@barryo Roger that! - thanks!

We are using a locally modified version for now.... just would prefer to be stock :)
