Vine: Unified Plotting Tool and Instructions

[dthain]

Per our most recent HEP-computing meeting -

We have a number of data sources and plotting tools for TaskVine, but no single "bright path" for users to follow when things go wrong. So:

• Create a single tool vine_plot_run that consumes all the logs in a single run (maybe even default to vine-run-info/most-recent/vine-logs) runs the existing plotting tools, arranges them nicely with some summary info, and emits a file: url pointing to an index.html that arranges and displays everything nicely.

(don't create new tools, just stitch together the things that we have.)

• Update our manuals to encourage this as the one single way to plot all of the things by default.

@JinZhou5042 per our discussion, please come up with a simple solution for this one.
