By default it assumes there is a redis server running on localhost at port 6379 and uses the database number 0.
It is possible to connect to a redis server using [[hostname]] and [[port]] or using a [[unixSocket]].
It also supports the AUTH command of redis.
When the server needs authentication, you can set the [[password]] property to
authenticate with the server after connect.
The execution of redis commands is possible with via Connection::executeCommand.
