    The name on this line that I am TMP-ing isn't the collection config name, it's the name of the collection. We don't want them to pass it but the collection param parsing code I'm reusing will barf (rightly) if there's no name for a collection. We'll fix that up later when we calculate the name for the initial collection in the Cmd class.

> This issue is about creating a single API command to create a "Time Routed Alias" along with its first collection.  Need to decide what endpoint URL it is and parameters.
> Perhaps in v2 it'd be {{/api/collections?command=create-routed-alias}} or alternatively piggy-back off of command=create-alias but we add more options, perhaps with a prefix like "router"?
> Inputs:
> * alias name
> * misc collection creation metadata (e.g. config, numShards, ...) perhaps in this context with a prefix like "collection."
> * metadata for TimeRoutedAliasUpdateProcessor, currently: router.field
> * date specifier for first collection; can include "date math".
> We'll certainly add more options as future features unfold.
> I believe the collection needs to be created first (referring to the alias name via a core property), and then the alias pointing to it which demands collections exist first.  When figuring the collection name, you'll need to reference the format in TimeRoutedAliasUpdateProcessor.
