Change SSDP discovery scan interval to 10 minutes (#99975)

* Change SSDP discovery scan interval to 10 minutes

The first version used a scan interval of 1 minute which we
increased to 2 minutes because it generated too much traffic.

We kept it at 2 minutes because Sonos historicly needed to
get SSDP discovery to stay alive. This is no longer the case
as Sonos has multiple ways to keep from going unavailable:

- mDNS support was added
- We now listen for SSDP alive and good bye all the time
- Each incoming packet from the device keeps it alive now
- We probe when we think the device might be offline

This means it should no longer be necessary to have such a
frequent scan which is a drag on all devices on the network
since its multicast

* adjust tests
