Change subject: IMPALA-12385: Enable Periodic metrics by default

IMPALA-12385: Enable Periodic metrics by default
This patch enables periodic metrics in query profiles by default and
changes the metric collectors to be more suitable for mixed workloads.
-Change default of resource_trace_ratio to 1
-Use samplng counters which can automatically resize for long queries
-Reduce metric interval to 50ms to support short-running queries
-Fragment metrics use the same sample interval as periodic metrics
Testing:
Updated runtime-profile-test and test_observability.py for new defaults
Manual inspection of query profile metrics for long-running queries
