Cannot update quotas using the XML API

[Sylvain Baubeau]

When one tries to update the quota set for a tenant, Cinder returns a "Quota limit must be specified as an integer value." error.

The request is a PUT to "PUT /v1/tenant_id/os-quota-sets/tenant_id" with the following body :

<?xml version="1.0" encoding="UTF-8"?>
<quota_set><gigabytes>1000</gigabytes><snapshots>10</snapshots><volumes>10</volumes></quota_set>

(This is the output of a GET on the same URL)
