Description
This small feature allows to pass a username to the RedisCluster constructor from the phpredis extension in order to be able to authenticate with a non-default user. Even though the README does not mention it, passing username and password in the form of an array is supported, see:
Without this feature, one could not connect to a cluster using a user other than the one named 'default'. When using RBAC it is recommended not to connect with the default user anymore by Redis.
This change should be backwards compatible in the sense that if no username option is specified, the phpredis extension will still connect with the default user.
