There were a couple of problems found by flake8 in the qa/
directory (most of them fixed now). Enabling flake8 during the usual
check runs hopefully avoids adding new issues in the future.

The task uses netem to emulate wide area network delay.
Provides three different configurable options.
1. standard delay: Constant delay with +/- 5ms jitter with normal distribution as default.
2. variable delay: To provide a delay between two given min-max range in milliseconds.
3. packet drop: Toggles packet drop and recovery in regular interval.
Useful in simulating network delays between two clusters while testing
rgw multisite and rbd mirroring configurations.
