usage_description="
Creates a TeamCity project

Idempotent - if the named project already exists, skips creation and returns success exit code zero

Uses the adjacent teamcity_api.sh

See teamcity_api.sh for required connection settings and authentication

If you need to delete a project you can call

    teamcity_api.sh /projects/NAME -X DELETE


Unfortunately you can't yet create a project from a saved configuration via the API, see this ticket:

    https://youtrack.jetbrains.com/issue/TW-43542
