 * Get valid project name

 * Checks that a project name isn't in use. If the name isn't in use, the passed string is returned. If the name is in use, this operation attempts to generate a valid project name based on the one supplied, usually by adding a sequence number. If a valid project name cannot be generated, a 404 response is returned.

**[Permissions](#permissions) required:** None.
