Subject: [PATCH 1/2] prepare bash completion for new TLS options

Up to now there were two special top-level options that required special
treatment: --project-name and --file (and their short forms).
For 1.7.0, several TLS related options were added that have to be passed
to secondary docker-compose invocations as well.
This commit introduces a scalable treatment of those options.
