Fix warning about STRICT_ALL_TABLES in mysql
Expose a volume for local configuration files

The user can now run docker run -P -v /data/phabricator_conf:/opt/phabricator/conf/local to be able to save these changes

For example /opt/phabricator/bin/config set phabricator.base-uri http://phabricator.local.com/ should now work
