Orchestrator: Proper handling for SAVE-cli issues reported by SAVE-agent

1. Right now if the processing fails we simply mark agent execution as CLI_FAILED
2. In this case orchestrator simply stops ALL agents (if all of them are IDLE or CLI_FAILED)
3. But tests are not marked as FAILED - they are still in RUNNING state

We need to do the following:

• Rename CLI_FALED to INTERNAL_SAVE_CLI_ERROR
• Mark tests FAILED (fail all of them)
• Think of how to give extra information to the user of what happened and why Agents failed
