Improved plugin error messaging

[joereuss12]

After talks with some facilitators, they told us ways to improve error messaging from the plugin. Now, all errors from the plugin now begin with PELICAN CLIENT ERROR as well as end with HOSTNAME and GLIDEIN_SITE

Before:

Transfer input files failure at the execution point using protocol osdf. Details: Error from 
slot1_7@glidein_253984_295706592@uct2-c516.mwt2.org: FILETRANSFER:1:non-zero exit (1) from 
/var/lib/condor/execute/dir_253982/glide_YoREfU/stash_plugin. |Error:  Failure downloading 
osdf:///chtc/staging/jrreuss/foo-v1.txt: failed connection setup: server returned 403 Forbidden 
( URL file = osdf:///chtc/staging/jrreuss/foo-v1.txt )|

After:

Transfer input files failure at the execution point using protocol osdf. Details: Error from 
slot1_6@glidein_3084899_80207786@build4002.chtc.wisc.edu: FILETRANSFER:1:non-zero exit (1) from stash_plugin. 
|Error:  PELICAN CLIENT ERROR downloading osdf:///chtc/staging/jrreuss/foo-v1.txt: failed connection setup:

Maybe hold off on a review until we get a format that everyone can agree on. Any changes requested should be an easy fix but I want to get a confirmed wanted hold message before I develop further.

@jhiemstrawisc This is ready for review now! Here is the updated message:

012 (11127448.000.000) 2024-04-02 09:19:07 Job was held.

With this being the Pelican piece:
Pelican Client Error: downloading osdf:///chtc/staging/jrreuss/foo-v1.txt: failed connection setup: Get "https://osg-gftp2.pace.gatech.edu:8443/chtc/staging/jrreuss/foo-v1.txt": net/http: timeout awaiting response headers (Pelican Version: 7.6.2; Site: Clemson-Palmetto)

• Note that the site does not show up if not run on the ospool (if there is no machineAd attribute GLIDEIN_Site)

A great addition that should be of benefit to users and facilitators alike!
