Vlad Lazar 08b19f001c pageserver: optionally force image layer creation on timeout (#12529)
This PR introduces a `image_creation_timeout` to page servers so that we
can force the image creation after a certain period. This is set to 1
day on dev/staging for now, and will rollout to production 1/2 weeks
later.

Majority of the PR are boilerplate code to add the new knob. Specific
changes of the PR are:
1. During L0 compaction, check if we should force a compaction if
min(LSN) of all delta layers < force_image_creation LSN.
2. During image creation, check if we should force a compaction if the
image's LSN < force_image_creation LSN and there are newer deltas with
overlapping key ranges.
3. Also tweaked the check image creation interval to make sure we honor
image_creation_timeout.

Vlad's note: This should be a no-op. I added an extra PS config for the
large timeline
threshold to enable this.

Local Development Control Plane (neon_local)

This crate contains tools to start a Neon development environment locally. This utility can be used with the cargo neon command. This is a convenience to invoke the neon_local binary.

Note: this is a dev/test tool -- a minimal control plane suitable for testing code changes locally, but not suitable for running production systems.

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.
