Introduction of report for k8s client

[ibrokethecloud]

Description

Why is this needed

Currently the k8s reporter is not implemented, as a result among other things the DisablePXE method is a no-op.

As a result in scenarios when leveraging custom-pxe, no DisablePXE is performed.

The PR introduces a reporter implementation of the k8s client. This allows the implementation for DisablePXE implementatino.

In addition, the OSIE / boots events are now also logged as k8s events associated with the hardware objects.

Fixes: #

How Has This Been Tested?

A simple unit test leveraging envTest is available which can simulate the events and hardware updates.

How are existing users impacted? What migration steps/scripts do we need?
