[8.0] fix: SSHCE.getPilotOutput()

[aldbr]

A minor fix that should allow us to get pilot outputs from SSHCE.
I remove the pilot stamp from the jobID if present.

I also realized that _ssh_call() was not working perfectly.

• I removed this line that seems to cause timeout exceptions: https://github.com/DIRACGrid/DIRAC/compare/rel-v8r0...aldbr:rel-v8r0_FIX_SSHCEConnection?expand=1#diff-d598e717337c370eeca523f2ea65fa780a2f7c90ebea3d62f8c5cd5d649c5779L150
• The same way, a few cases do not seem to be properly handled like Connection refused for instance (I did not change that).

There exist a few popular python libraries to perform SSH operations like Fabric (Paramiko) (https://docs.fabfile.org/en/stable/). Wouldn't it be more reliable that our _ssh_call() method?

Probably... but this looks like a task that you might want to look into later on.
