Metalnx fixes 1

[JustinKyleJames]

This is to fix multiple issues as seen in the commits.

Notes:

1. The main issue with 307 has been resolved. I did not get all of the dependencies upgraded but did update some.
2. The fix for 355 is a workaround for Jargon issue 495.
3. I will add more issues before Trirods if time permits.
4. This requires updates to both jargon and jargon-irods-ext. Pull requests for these have also been opened.

jargon-irods-ext PR: DICE-UNC/jargon-irods-ext#49

Will review this soon.

Nice, looks like a lot of improvements in here.

Sorry if we've gone over this before, can't recall... Are there automated tests we can add for this, or is it mainly manual at this point? And speaking of which, have the issues in question been tested and shown to be fixed?

Looks like this PR just needs the jargon and jargon-irods-ext PRs to land now.

I squashed the commits.

Probably should wait for @korydraughn's approval before #'ing.

When #'ing, don't forget to add #'s to both issue numbers on that last commit so that they link.

Pound it.

Don't forget to add the pounds in the commit message body as mentioned by @alanking.
