[FeatureRequest] Run in transparent mode.

[tsyganov-ivan]

Hi! Thanks for a great job!
Everything is working well.

I've one idea and want to know the community's opinion.
What if on run pethublocal we will make a request to surepet cloud, receive credentials to their mqtt and make second connection to it. We can resend all messages from local queue to cloud queue and almost all messages from cloud to local queue.

Why I think this is a useful feature:

• original app will be working (at least for a while)
• push notification will continue working
• it helps with analysis packages, which are not supported yet

Of course, this feature should be optional.
If the community will be interested in this feature I can do it by myself and send PR to the main repo.

As a second option I can make a small side-service for proxying packages from/to the cloud.

I did look into the option of creating a client to connect to "the real cloud" but there are a few issues around managing the device counters and sending Home Assistant initiated requests to the hub / device incrementing the counters but then the real cloud sends an update using the same counter.

In regards to MITM the traffic, I documented that all here.

Will bring all the PolarProxy stuff over here.
