Docker CLI commands run as user root still about vessel HOT 2 CLOSED

Gonna have to get fancy with this issue similar to how MySQL does, using gosu.

Example installation here: https://github.com/docker-library/mysql/blob/86431f073b3d2f963d21e33cb8943f0bdcdf143d/8.0/Dockerfile#L6-L17

Additionally:

1. ENTRYPOINT script should run as root to correctly create/destroy symlinks
2. exec call to composer, phpunit, artisan should use gosu to run command as $WWWUSER
3. app container should have a /.composer directory created & chmod -R ugo+rw'ed

This will be done in PR #21

from vessel.

Fixed in #21
