Setup misses config options for Redis/Memcache

[philicious]

The setup script https://github.com/dreamfactorysoftware/dreamfactory/blob/master/app/Console/Commands/Setup.php#L17 invoked via php artisan dreamfactory:setup misses config parameters for Redis (and likewise for Memcache as mentioned in #31, however I cant even find Memcache options in https://github.com/dreamfactorysoftware/dreamfactory/blob/master/.env-dist).
You can only set --cache-driver via the CLI installer.
One can work around this for sure but its not convenient for unattended installs or with https://github.com/dreamfactorysoftware/df-docker

Added memcached config in environment. Updated the setup command to accept redis and memcached config options. The changes are in develop branch. This should be available in next release.
