Missing features

[mlankipalli]

• Add duration as argument for the profiling.
• Add output_dir to store the results in given path
• Add how to read the metrics collected by aperf?
• single command for both record and report, its useless to have recording data without report, then why to have a separate command for record alone?
• colour code the obvious performance issues from the collected events.

1. What is the reason for the argument for profiling. Currently, aperf profiles for the duration of the run.
2. output_dir is used with default aperf given names?
3. Currently no support exists to read aperf collected metrics independently.
4. We separate the record and report so as enable users to only run record on sut. The report can be generated from any linux machine. aperf report has overhead which should be avoided for all users.
5. We can consider adding this.
