We will now store default quotas in default-project.
It will be overwritten every time api server is restarted. Earlier, we were writing configured values in each project which makes us not able to distinguish between the cases where quota values are set on that project or not. As a result, subsequent updates to quota values were not being applied to existing projects.

With the new change, we will for each resource, we will first check if it is configured for that project. If not, we will check the default-project (which is configured through the config file), then finally code default value of -1
