Use the same data source as Home Assistant

Description

Quickfix to, at least, share the API calls with the main Hue integration, using the sensor manager coordinator form there.

Even without increasing the SCAN_INTERVAL's used here, this should reduce a bit the induced stress in the Hue bridge.

Relates to #220 and #215

Notes

• It does not address anything more than the API call, for now.

Yeah, no problem. It seems related to attrs version someway (result of the bumping, I suppose, but local tests pass)
