Now nova coverage is standardized to accumulate coverage data.
It enables user to get combined coverage data of several tests.
In addition to it, we need to restart nova services when measuring
coverage of each test because there is no function to reset data.
This adds reset coverage data API.

This makes a few minor cleanups and 2 additions to the
coverage extension. First, it adds a new optional field to the
report action: 'html'. This will generate an html report instead
of either the text or xml reports that the extension can
generate.
The second change is that it adds a return for the stop action.
Now upon successful completion of the stop action the directory
where the coverage data files will be returned.
