Commit Message

fix: allow read-only operations when all masters are down

Read-only operations (get, select, count, min, max) used to fail with
connection errors if all masters in the cluster were unavailable, even
when healthy replicas were up and failover hadn't processed yet.

To resolve this, the following improvements were made:
- Introduced a `read_only` flag to `utils.get_space[s]` to fetch cluster
  schema from any healthy replica if masters are down.
- Updated `get`, `select`, `count`, `min`, `max` to use this new flag.
- Rewrote `call.any` to iterate through all replicasets and utilize
  vshard's `callro` instead of `call` to fetch metadata from replicas.
