Add summary to worklow watch

What was changed

Added workflow execution summary to trace command.
Depends on #233.

Why?

To provide important information about what workflow execution is traced. This could be extended to include other information as StartTime (or a diff with now).

you should be able to accomplish ~same result with an existing API, ex.

cli/cluster/cluster_commands.go

Line 61 in f8c84ed

return output.PrintItems(c, []interface{}{cluster}, po)

Have you also considered using it?

[sebneira]

Done!

Btw, I found it a bit tricky to implement PrintItems since I didn't find any docs. Am I missing something?

[feedmeapples]

yea it was not documented. Designed this way to accept user's input in a simple form
Let me look into documenting this better

[feedmeapples]

pushed few commits to make PrintWorkflowTrace easier to read (and address golangci-lint failing on complexity). There is an issue with execution updates after my commits, addressing these and merging

Hi 👋
Is there any updates on this PR?

Thanks

I would consider a flag to skip printing the summary but otherwise LGTM.

Thanks.
