Code coverage to expose project

[Ronald Bradford]

When generating code coverage (i.e. npm test) the cover HTML output does not give any indication to the project to which the output belongs when viewing the coverage report.

Ideally a wish list would be to indicate the specific project in a header.

Currently python code coverage (e.g. http://logs.openstack.org/38/212738/12/check/designate-coverage/bc2e329/cover/ and http://logs.openstack.org/82/165682/8/check/nodepool-coverage/08c6340/cover ) it can be determined which project by the prefix of the filenames.
