Describe the bug
A clear and concise description of what the bug is.
The variable PELICAN_CLIENT_PREFERREDCACHES to specify a specific cache for e.g. testing as documented is ignored by both the pelican client and the HTCondor plugin.
The older PELICAN_NEAREST_CACHE is respected by the client and the plugin.
To Reproduce
Steps to reproduce the behavior.
From the docs use:
environment = "PELICAN_CLIENT_PREFERREDCACHES=https://address.to.desired.cache:port"
in an HTCondor job or just set it at execution time with e.g.:
$ PELICAN_PREFERRED_CACHES="https://address.to.desired.cache:port" pelican object get osdf:///some/path
Expected behavior
A clear and concise description of what you expected to happen.
The client and plugin for this version (7.20.2) should use the cache specified in PELICAN_PREFERRED_CACHES (as they do for PELICAN_NEAREST_CACHE)
