Add new `pod-info` command.

[jlojosnegros]

This command will allow us to gather some pod information filtered by node.

The pod information gathered is filtered with a go-template. Right now that template is hard-coded but it would be easy to use an incoming param to read it from a file name if needed in the future. Pod information is filtered because we want to avoid to show sensible information in the must-gather tool.

When, if ever, change the output go-template consider: 1.- this output is going to be parsed at must-gather-pao so any change should be carefully synced 2.- be sure no sensible information is in the final output (like environmental variables or command parameters that can contain passwords)

Target for this PR is to create a command to gather the same info as with openshift-kni/performance-addon-operators#906 but without using raw oc commands
