## Problem
We don't have an alert for long running reconciles. Stuck reconciles are
problematic
as we've seen in a recent incident.
## Summary of changes
Add a new metric `storage_controller_reconcile_long_running_total` with
labels: `{tenant_id, shard_number, seq}`.
The metric is removed after the long running reconcile finishes. These
events should be rare, so we won't break
the bank on cardinality.

Control Plane and Neon Local
This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command.
Example: Start with Postgres 16
To create and start a local development environment with Postgres 16, you will need to provide --pg-version flag to 3 of the start-up commands.
cargo neon init --pg-version 16
cargo neon start
cargo neon tenant create --set-default --pg-version 16
cargo neon endpoint create main --pg-version 16
cargo neon endpoint start main
Example: Create Test User and Database
By default, cargo neon starts an endpoint with cloud_admin and postgres database. If you want to have a role and a database similar to what we have on the cloud service, you can do it with the following commands when starting an endpoint.
cargo neon endpoint create main --pg-version 16 --update-catalog true
cargo neon endpoint start main --create-test-user true
The first command creates neon_superuser and necessary roles. The second command creates test user and neondb database. You will see a connection string that connects you to the test user after running the second command.
