Performance Improvements

• CPU Performance Fix: Implement SSH multiplexing for all jobs, especially CheckServerJob, resulting in 50% faster execution of the ServerCheckJob (1s+ down to 0.5s or less) and reduced CPU consumption
• CPU Performance Fix: Optimized SSH key handling to avoid unnecessary disk writes when executing remote commands (since the SSH key was written to disk each time a remote command was executed, this is no longer the case).
