We currently report nodepool resource usage whenever we use or return nodes. This now happens on the executors, and they don't have a global view of all nodes used. The schedulers do, and they already have a periodic stats reporting method. Shift the reporting of node resource gauges to the scheduler. To make this efficient, use a tree cache for nodes. Because node records alone don't have enough information to tie them back to a tenant or project, use the new user_data field on the Node object to store that info when we mark a node in use. Also, store the zuul system id on the node, so that we can ensure we're only reporting nodes that belong to us. Update the node list in the REST API to use the cache as well, and also filter its results by zuul system id and tenant.
