Binary sensors for netgear_lte

[amelchio]

Description:

Follow-up to #22558 where @rohankapoorcom pointed out that some of the sensors should have been binary sensors. Since #22558 is not released yet, this is not a breaking change.

Most of the changes here are due to moving shared methods to a base class in the component. The rest is a binary_sensor implementation, mostly copy/pasting the existing sensor implementation. I did not split into several PRs mostly because the clock is ticking on the next beta.

Pull request in home-assistant.io with documentation (if applicable): home-assistant/home-assistant.io#9178

I am in doubt about the proper device class to use here. The UI currently shows a checkmark when roaming and that seems odd. However, "roaming" is the terminology normally used so I see no way of reversing the naming without causing confusion.

[MartinHjelmare]

I don't have a better solution here.

[amelchio]

@MartinHjelmare I don't normally ask for reviews but it would be good to get this in before the beta and it is mostly small changes to code that you already reviewed, so if you have the time ...

[amelchio]

Thank you. I added the documentation update now.
