These are the perf counters added in commit 263dfba6ee.
Note: This relies on 'neon' extension version 1.5. The default was
bumped to 1.5 in commit d696c41807.

On bookworm, 'cmake' is new enough that we can just use it. On bullseye,
we can get a new-enough package from backports. By including 'cmake' in
the build-deps stage, we don't need to install it separately in all the
later build stages that need it.
See https://github.com/neondatabase/neon/pull/2699, where we switched to
downloading and building a specific version.
## Problem
We need the
[pg_session_jwt](https://github.com/neondatabase/pg_session_jwt/)
extension in the compute image. This PR adds it.
## Summary of changes
I added the `pg_session_jwt` extension in a very similar way to how the
pggraphql and pgtiktoken extensions were added (since they're all
written with pgrx). Then I tested this.
```

Part of https://github.com/neondatabase/cloud/issues/13127. Resolves
#9153
What changed in this PR:
1. Adds `ComputeSpec.disk_quota_bytes: Option<u64>`
2. Adds new arg to compute_ctl: `--set-disk-quota-for-fs <mountpoint>`
3. Implements running `/neonvm/bin/set-disk-quota` with the right value
if both cmdline arg AND field in the spec are specified
4. Patches `/etc/sudoers.d` to allow `compute_ctl` to set quota with
sudo
This PR is very similar to the swap support added earlier, you can take
a look at it as prior art: #7434
In theory, it can be implemented outside of compute_ctl when we will
have a separate neonvm daemon, but we are not there yet. Current
implementation is the simplest possible to unblock computes with larger
disks.
All code related to usage of `/neonvm/bin/set-disk-quota` is located in
`disk_quota.rs`. We need to call this script with the following
arguments: `/neonvm/bin/set-disk-quota {size_kb} {mountpoint}`. Quotas
are set on the filesystem level, so we need to provide path to the
directory that filesystem was mounted to.
I tested this change locally with
https://github.com/neondatabase/cloud/pull/17270. It should be safe to
merge, because this feature is gated by both cmdline arg and field in
the spec. If control-plane doesn't set values in both places,
compute_ctl won't be affected by this change.
## Problem
All the other patches were moved to the compute directory, and only one
was left in the patches subdirectory in the root directory.
## Summary of changes
The patch was moved to the compute directory as others
Instead of adding them to the VM image late in the build process, when
putting together the final VM image, include them in the earlier
compute image already. That makes it more convenient to edit the
files, and to test them.
Seems nice to keep all these together. This also provides a nice place
for a README file to describe the compute image build process. For
now, it briefly describes the contents of the directory, but can be
expanded.
