Increase dependency versions where not covered by auto-update

[kate-goldenring]

Akri's dependencies should be updated. While our auto-update workflow follows semver for updating patches and minor versions where possible, the following crate versions need to be updated:

• udev to 0.6
• async-stream in Agent
• tonic, tokio, warp (0.3 requires tokio 1.0), futures, prost, hyper which are interdependent and non-trivial to bump
• actix in Webhook
• yaserde in ONVIF discovery handler

Akri's Python and .NET sample brokers and apps should also be inspected for version updates.

In the udev Discovery Handler, a Enumerator trait was created in order to mock the udev crate's Enumerator struct. Updating udev to 0.6.0 requires changing the scan_devices function definition in the Trait to match the new definition.
FROM
fn scan_devices(&mut self) -> std::io::Result<udev::Devices>;
TO
fn scan_devices(&mut self) -> Result<List<'_, Enumerator, Device>>;
which requires reconciling lifetimes

We cannot update to the latest versions of kube-rs and k8s-openapi because kube-rs requires that all fields of a CRD Spec derive JsonSchema; however, k8s-openapi structs do not. Consequently, any CRD specs that contain K8s objects (such as PodSpec and ServiceSpec structs in ours) do no compile. There is an issue up on k8s-openapi to support JsonSchema that will need to be resolved before we can proceed with updating our dependencies. This fix Arnavion/k8s-openapi#104 works as I am able to compile everything by patching k8s-openapi with the PR branch.

Closing due to all dependencies being updated besides udev which now has its own issue: #364
