Add required_files to addName

[natefoo]

Although the quoting is valid, I think the way it's done prevents Pulsar from implicitly copying the wrapper script? On .org we're getting:

python: can't open file '/jetstream2/scratch/main/jobs-vgp/70483536/tool_files/add_input_name_as_column.py': [Errno 2] No such file or directory

This adjusts the quoting and adds required_files for good measure. No tool version change because there's no change in functionality, just a fix for running with Pulsar.

Heh, lint failed because I didn't update the version.

I do get why we require this but it's a bit annoying to have two identical versions installed except one works half the time and the other doesn't. Obviously I can deal with this on my end in multiple ways, however.

We can merge. The linter is skipped when merging.

Now that the older version can not be used anymore.

Do all tools that use __tool_directory__ should have required_files?

Someone (@jmchilton) correct me if I'm wrong, but yes I believe that is the desired state. Pulsar will implicitly find, transfer, and rewrite files used in the <command>, but going forward I believe the goal is to have them explicitly referenced.
