The dense format of runtime profile print instance names in single long lines. It is hard to observe the instance names, especially when a fragment has many instances. This patch fixes the issue by breaking the list into multiple lines, one line per instance. We also prefix the instance names with an index number for easy matching against pretty-printed counters, events, and info strings. Testing: - Fix and pass observability/test_profile_tool.py. - Manually verify that impala-profile-tool prints the instance names in multiple lines.
