I'd rather return an empty array here and keep the return type consistent.

Is there a reason to call this force_name versus alias_name?

Because an index name could also be used. It is an overwriting from the name on the config file.

To be able to migrate indexes with no downtime we need to be able to use aliases and to create indexes with custom names on ES. This PR adds the possibility of using custom names (outside of config) and adds methods to be able to get to the index reference (for creation and deletion) if using an alias.
