Get the quotas for the named folder.
Quotas are controlled on the basis of a quota root, not
(necessarily) a folder.  The relationship between folders
and quota roots depends on the server.  Some servers
might implement a single quota root for all folders owned by
a user.  Other servers might implement a separate quota root
for each folder.  A single folder can even have multiple
quota roots, perhaps controlling quotas for different
resources.

Params:
  • folder – 	the name of the folder
Throws:
Returns:		array of Quota objects
