Fix missing latency metrics from other namespaces

[ian28223]

What does this PR do?

Fix missing latency metrics from other namespaces. This allows the check to continue processing next lines following an invalid line. Example, {foo}-pi-query: line is considered invalid (due to regex not matching) and prevents following lines with potentially valid metrics from being processed.

latencies: batch-index:msec,172.1,0.06,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00,0.00
