Fixes bug 1075369. During quota check we used to simply retrieve the entire collection of resources from the database, then counting them in Python. This patch introduces a specialized _get_collection_count() method, which instead take advantage of the DB's built-in count capabilities. In order to take advantage of this, plugins can now implement get_*_count() methods for their resources. This is used (if present) by the quota checking function. Patch incorporates review feedback from Dan W, Alex Xu, Zhongyue Luo, Edgar Magana, Akihiro Motoki and gongysh. Change-Id: I87e2d0294e116e8147fed2ee90c9eb0cf1a54362
