Re-work CTA log line format

Compile and Running CTA in Alma9 Linux

• Julien will check with Marc and explore using iSCSI (on a separate VM/host) for MHVTL.

Add CTA regression test with and/or to EOS

• Julien will create tucket with a clear proposal for discussion with the EOS team. It should contain only the CTA frontend, to keep it simple, and not depend on MHVTL.
