tools: websocket: Add dummy and build integration

Adding support for Shelly devices requires usage of the Websocket API.

To make development easier a debug tool is created.

Since it is not relevant for users it is not an artefact included into
the deploy file archive. This also avoids later removing it which is by
definition of the public API (see README.md) a breaking change.
