This commit addresses multiple issues in the RunHostTest execution flow:

1. Fixed console prompt mismatch in OpTestUtil.try_command()

   • Use pre-built term_obj.expect_prompt instead of rebuilding
   • Ensures consistency between terminal PS1 and expect pattern
   • Resolves command hangs caused by prompt pattern mismatch

2. Added use_direct_ssh parameter to OpTestSSH.run_command()

   • Allows console-based execution for session persistence
   • Maintains working directory between command executions
   • Default True for backward compatibility

3. Updated RunHostTest to use console-based execution

   • Set use_direct_ssh=False for all run_command() calls
   • Skip empty lines and comments in command files
   • Ensures cd commands persist across executions

4. Fixed false PETITBOOT state detection in OpTestSystem

   • Added console=1 parameter to host_run_command()
   • Prevents unnecessary system reboots during tests

5. Prevented duplicate OS sysinfo collection in OpTestHMC

   • Added sysinfo_collected flag to track collection state
   • Check flag before collecting in set_system()
   • Eliminates duplicate sysinfo output and improves performance

These changes restore the original console-based execution behavior while maintaining compatibility with the SSH migration.
