[AWARE] Test-wide configuration for power & startup offset

Add global configuration to all tests - passed through the
configuration file:

1. Power state: sets the power state of the discovery window (DW)
   configuration. May be overriden in the test itself.

2. Synchronized start-up may result in longer discovery as both
   devices stop scanning at the same time, form their own cluster,
   and don't scan until much later. Provide a global configuration
   of an offset startup time.

   - Setting can be overriden in specific tests.
   - A test will be added to measure its impact
   - All tests should be run for 0 offset (same startup) as well to
     measure impact.
