John Spray 8dca188974 storage controller: add metrics for tenant shard, node count (#9475)
## Problem

Previously, figuring out how many tenant shards were managed by a
storage controller was typically done by peeking at the database or
calling into the API. A metric makes it easier to monitor, as
unexpectedly increasing shard counts can be indicative of problems
elsewhere in the system.

## Summary of changes

- Add metrics `storage_controller_pageserver_nodes` (updated on node
CRUD operations from Service) and `storage_controller_tenant_shards`
(updated RAII-style from TenantShard)
