trace_processor: add support for text proto out and interactive metrics

This CL adds support for two features which make developing metrics a
lot easier:
1. textproto output: this is crucial for a tight feedback loop when
looking at the output of metrics.
2. interactive mode: we extend the -i flag to --run-metrics so users can
query their views after they run their metric
