Meadow.Cloud - OTA Update events triggering multiple times

[jorgedevs]

You can trigger the Meadow.Cloud's OTA Update events multiple times if/when you publish an update multiple times, causing the device to download the update more than once.

Might be a good idea to add logic to either cancel an ongoing update to get a newer incoming update, ignore subsequent incoming update events if one is processing, just queue the updates, or any other alternative. Not sure what option makes most sense.

We need to reason whether we want to serialize multiple updates, or disregard all but one.
