Skaffold should output which kube-context + cluster is being used

[briandealwis]

It should be more clear for users (and people trying to offer support by looking at logs!) which kube-context and cluster is being used.

$ skaffold dev
Listing files to watch...
 - skaffold-example
Generating tags...
 - skaffold-example -> skaffold-example:v1.34.0-60-gef8185519
Checking cache...
 - skaffold-example: Not found. Building
Starting build...
Building [skaffold-example]...

This information is shown with -vinfo, but most users do not run at this level:

$ skaffold dev -v info

Can I take a stab at this?

@OmSaran that would be great if you want to drive adding this feature. If you could create a PR with this feature the Skaffold maintainers would be happy to review and get the feature in. If you have any questions, etc. about the implementation feel free to ask questions, etc. here

@OmSaran and I have taken a stab at this issue, please see PR #8587
