Introduce new V2 spec file format.

This includes code that can still read the old V1 format, and convert
it to the new ComputeSpecV2 struct.

For better test coverage of the upgrade function, update the sample V1
cluster spec file in the tests to match more closely what the control
plane actually generates.

The intention is to change the real web console to also use the V2 format,
and then remove the support for V1 format altogether.

+//! Code to manage compute endpoints
+//!
+//! In the local test environment, the data for each endpoint is stored in
+//!
+//!   .neon/endpoints/<endpoint id>
+//!
+//! Some basic information about the endpoint, like the tenant and timeline IDs,
+//! are stored in the `endpoint.json` file. The `endpoint.json` file is created
+//! when the endpoint is created, and doesn't change afterwards.
+//!
+//! The endpoint is managed by the `compute_ctl` binary. When an endpoint is
+//! started, we launch `compute_ctl` It synchronizes the safekeepers, downloads
+//! the basebackup from the pageserver to initialize the the data directory, and
+//! finally launches the PostgreSQL process. It watches the PostgreSQL process
+//! until it exits.
+//!
+//! When an endpoint is created, a `postgresql.conf` file is also created in
+//! the endpoint's directory. The file can be modified before starting PostgreSQL.
+//! However, the `postgresql.conf` file in the endpoint directory is not used directly
+//! by PostgreSQL. It is passed to `compute_ctl`, and `compute_ctl` writes another
+//! copy of it in the data directory.
+//!
+//! Directory contents:
+//!
+//! ```ignore
+//! .neon/endpoints/main/
+//!     compute.log               - log output of `compute_ctl` and `postgres`
