add asset type to cnspec output (especially for k8s assets)

[DrackThor]

Describe the bug
The output of k8s scan results can be misleading or hard to interpret, because assets of different types might have the same namespace/name identifier.
Eg a deployment "test" in namespace "my-namespace" and it's assigned service (also named "test"), both have the same cnspec output asset identifier of "Asset: my-namespace/test"

To Reproduce
Steps to reproduce the behavior:

1. have a k8s cluster available
2. run cnspec scan k8s -f mondoo-kubernetes-best-practices.mql.yaml > issue.txt

If you have a look at the "Kubernetes Service" objects, you will find that there are no checks specified for them (perfectly fine).
When you copy one service identifier and look for the detailed output of that asset, somewhere above in the file, you will see something like:

Asset: my-namespace/test
-----------------------------------------

error: rpc error: code = InvalidArgument desc = asset doesn't support any policies

If I didn't know that this is an asset of type "Kubernetes Service", I'd have no idea at what I'm looking.

Expected behavior
Please add the asset type somewhere in the output, maybe something like this:

Asset: (Kubernetes Service) my-namespace/test
-----------------------------------------

error: rpc error: code = InvalidArgument desc = asset doesn't support any policies

Screenshots or CLI Output

I cut one ouf our LAB cluster scans to the necessary parts:

# <- Kubernetes Deployment
Asset: my-namespace/test
---------------------------------------

Checks:
✓ Pass:  100  Container should request CPU
✓ Pass:  100  Pod should not define hostAliases
✕ Fail:   80  Container should configure a livenessProbe
✕ Fail:   80  Container should configure a readinessProbe
✓ Pass:  100  Deployments should not bind to a host port
✓ Pass:  100  Deployments should not run in the default namespace
✓ Pass:  100  Container should request memory

# <- Kubernetes Service
Asset: my-namespace/test
--------------------------------------------

error: rpc error: code = InvalidArgument desc = asset doesn't support any policies
