Note: The web socket example does not work when using OTEL HTTP. Here is an issue related to that on open-telemetry/opentelemetry-js-contrib.

Websocket event support for cleaning up pods only after WS connection is terminated. The support for websocket is right now in the environment itself and router simply acts as a proxy for WS communication!
This feature enables routing more than one request to a pod at the same time. This is the first draft of the work and might involve more optimizations later.
In some cases, creating a package and querying the package info
immediately the Kubernetes API server will return "not found"
error. So retry the query again after some time.
In the case of large files, it takes a long time for the user to download
the source from the URL and upload it to StorgeSvc through CLI.
This PR allows a user to use URL as the function source when creating a function
and provides a new flag "--keeparchiveurl" to let the user to decided
whether the CLI should download the file first or store the file URL in the
archive directly. If "--keeparchiveurl" is true, then no checksum will be
generated, it's the user's responsibility to ensure the file won't be changed.
