add option to remove NetworkCapabilities.NET_CAPABILITY_INTERNET

[phatpaul]

My use-case is connecting to a ESP32 AP and flashing firmware OTA. So the AP I'm connecting to does not provide internet connectivity.

This example android code includes this line:
.removeCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET)

Would that be helpful for some devices to maintain their primary internet connection (i.e. cellular data) while connected to the ESP32?
Can we have that as an option through this plugin?

Unrelated question: my ESP32's AP often becomes unstable during FW upgrade, is there a way to be notified or query when the WiFi connection is broken so I can try to connect again?

+1. many apps trying to connect to local wifi would prefer to not disrupt internet connection, be it a devece config app or a intranet business app, but there was no such option possible.
