Add api endpoint that expose the list of projects with their license usage

Implement new endpoint: api/projects/license_usage
Available only for Admins in DE+
Only works for Projects, Apps and Portfolios are not taken into account for license usage.

The supported type of output file is only CSV.

It returns a list of projects and, for each, the following fields:

• Project Key
• Project Name
• Biggest Branch or PR name
• Lines of code on the branch/PR:
  We can leverage LiveMeasureDao.sumNclocOfBiggestBranch() for this
• Lines of Code LOC / Max LOC in the license (license.getMaxLoc()) in %
• Last Activity Date on the Branch/PR
  Last Analysis can be queried from snapshots table

Example output file:

Project Key,Project Name,Branch Name,Lines of code,License usage,Last Active Date
