Clean UI

[CannonLock]

Add in the code and password creation section of the pelican ui

@CannonLock - I think you might want to back out the last commit. It introduces a wholesale reformat of the code base (maybe something your editor did?) and removes a bunch of entries from go.sum. The latter is breaking the build.

I've got a separate branch locally for doing the wholesale reformat. Let's keep this one just to the initial UI.

@CannonLock - did a rebase to clean up the PR. However, the build itself is failing on my local environment:

This is an EL7 host -- I suspect the node and npm versions are now considered ancient and are the culprits for the failure. Do you know what a minimum working version would be?

[bbockelm]

Actually, scratch that. I just did a blind update from EPEL and now have a new enough version to work -- no need to debug old cruft.

I'd like to get the framework for the UI merged in so approving right now.

However, it seems that the gin routes aren't configured correctly -- it's not actually serving up the pages as expected (e.g., even just the index page at / is blank in my testing). It could be my fault - maybe something got lost by the rebase?

Here's what I'm doing for the test:

osdf -d -f osg-htc.org origin serve -v /tmp/test:/test

Regardless, I'm approving for now so the fixes for the display issue are a small patch to review.
