Update get_quota to handle grace values

Update get_quota to support output from the `quota` command that
includes values in the grace columns. These columns have been empty for
ext4 volumes, but with xfs volumes, they can have a value, and that was
causing get_quota to return incorrect values for certain fields. Add the
-p flag to the quota call so the grace columns always have a value.

Fix bug 1129394.

cloud_user: enable normalization of user logins.

https://trello.com/c/noKWhxNG/212-2-enable-custom-normalization-of-usernames-from-external-sources

This enables an administrator to define a custom method to normalize
usernames before they are translated into cloud_user entries.

For example, this method could downcase the login such that the login
is case-insensitive; then case-insensitive authentication methods would
not create multiple cloud_users for the "same" login just because the
user capitalized it on one occasion and not another.
