Revisit condor shadow hooks with plugin staging

[joereuss12]

Making this an actual issue so that I can aim to do it. For v7.6.0 I want to revisit condor's shadow job hooks with our Pelican plugin staging to see if we change a file on an origin that we can detect that and change the file. Cole's changes to condor file transfers are making progress but not fully implemented however, we should start working on this again so that we can see if this works how we want it to and just make changes when needed.

Also we need a unit test for plugin staging, merging those two tickets into this one

Making a note here:
We can make a test for this using our federation in a box however, how it is currently written it cannot work. It most likely will work with this PR being merged: #798, because of the changes to how we handle metadata and it would work with an osdf:// url and prefix. It will work because it will load the metadata from config since it should be set already and not completely rely on topology. Therefore, we can set our fed in a box to config and utilize that to run this as a test locally.

Note: Got a successful test run on HTCondor AP submit4! All that is needed now to complete this PR is a test but currently waiting on #798 to be merged first

This needs revisiting in terms of the logging. The rest should be good and needs a review soon
