adds (root) account-level setting for (default) user file quotas. defaults
to 50 MB.
test plan:
1. on a root account, change the default user quota to something other
than 50 MB (e.g. 1 MB)
2. as a user in that account:
1. go to /users/self/files/quota . you should see the new quota
2. attempt to upload files. once you have hit/exceeded the quota, you
should not be able to upload additional files
3. as a user in multiple (root) accounts:
1. go to /users/self/files/quota . your quota should be the sum of the
root account user quotas
2. attempt to upload files. once you have hit/exceeded the quota, you
should not be able to upload additional files
note that the previous behavior does not change in that one file can exceed
your quota. e.g. if your quota is 1 MB, you can upload a 2 MB file. only
then will you be prevented from uploading additional files
