Performing stress test on mainline for 1 pcore support, it was
noticed that the metrics-server pod is restarting due to low
default timeout (1 second).
Increasing this value to 10 seconds will have no impact on app
performance, but will delay restart in case of probe failure.
Test Plan:
PASS: build metrics-server packages
PASS: install metrics-server updated and check the
livenessProbe and readinessProve timeout.
