    yeah, this is stuff that the collection create code adds. I'll look if I can use constants
from there and make a set out of them.

> 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
> 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.
