Switch license to CC

This changes the specs repo default license to be CC instead of apache.
Update index to make it more legible

This commit changes the organization of the index to make it clear
what is documentation and what is a spec file.
Add new project_name variable to cookiecutter

This commit adds a new cookiecutter variable to specify the targeted
lp project that specs in the added repo are targetted against. For
example if the repo_name was nova-specs project_name would be nova
or for qa-specs it would be tempest.
Add a template spec

This commit adds a basic template based on the one in the qa-specs
repo. It obviously won't be exact for every project but it gives a
starting point.
