… remote_command -t replica-server replica.query-compact shell command.

What problem does this PR solve?

#2190

What is changed and how does it work?

The commit 2d68748 changed the output format of the shell command remote_command -t replica-server replica.query-compact ${app_id}, which caused the wait_manual_compact function to still parse the output based on the original format, leading to incorrect behavior. It has now been fixed by modifying the parsing method.

The shell command remote_command -t replica-server replica.query-compact ${app_id} outputs in the following format in the latest version:
