Allow supplying pipeline argument positionally

[patrobinson]

Usage:
  bk build view <number> [pipeline] [flags]

I should be able to supply pipeline without having to supply the number argument.

@patrobinson just going through open issues and wanted to check in on this one; we support bk build view -p PIPELINE_SLUG. Does that solve this or would you want to not have to use a -p flag?

I'm going to close this out as done given there is an option to pass in just the pipeline with -p. You're welcome to reopen this if you feel it doesn't solve the initial issue. 🙂
