update to use latest konnected py module

[kit-klein]

Proposed change

We noticed during load testing that the async konnected py module could overload the http stack inside konnected panels with too many simultaneous requests. When this happens CannotConnect exceptions are raised within the konnected component and the state change attempt will fail.

To mitigate this we updated the konnected py module to throttle state change attempts (max 3 at once) and retry upon failure. This completely resolves the issue.

This PR updates the konnected component to use this latest konnected py module (1.2.0).
