For core K8s API objects like Pods, Nodes, etc., we
can use protobuf encoding which reduces CPU consumption
related to (de)serialization, reduces overall latency
of the API call, reduces memory footprint, reduces the
amount of work performed by the GC and results in quicker
propagation of objects to event handlers of shared informers.

When NewK8sClient() detects and error, it used to call FatalLogMsg()
which causes a panic. There are additional features that can be used on
Kubernetes clusters, but these are not a requirement for most
functionalities of the driver.
Instead of causing a panic, returning an error should suffice. This
allows using the driver on non-Kubernetes clusters again.

By placing the NewK8sClient() function in its own package, the KMS API
can be split from the "internal/util" package. Some of the KMS providers
use the NewK8sClient() function, and this causes circular dependencies
between "internal/utils" -> "internal/kms" -> "internal/utils", which
are not alowed in Go.
