Fix ansible server config

Added ansible server to docker-compose.yml and made a few config changes:
 - redirect of output in final exec causes exec to fail.  Instead, need
   to redirect output in standalone exec line.  Redirected to
   /var/log/ansible-server.log
 - Updated LCM config to use ansiblehost alias to reach ansible
   (was incorrectly using 0.0.0.0)
