nixos: ec2 ami: support IMDSv2
AWS's metadata service has two versions. Version 1 allowed plain HTTP
requests to get metadata. However, this was frequently abused when a
user could trick an AWS-hosted server in to proxying requests to the
metadata service. Since the metadata service is frequently used to
generate AWS access keys, this is pretty gnarly. Version two is
identical except it requires the caller to request a token and provide
it on each request.

Today, starting a NixOS AMI in EC2 where the metadata service is
configured to only allow v2 requests fails: the user's SSH key is not
placed, and configuration provided by the user-data is not applied.
The server is useless. This patch addresses that.

Note the dependency on curl is not a joyful one, and it expand the
initrd by 30M. However, see the added comment for more information
about why this is needed. Note the idea of using `echo` and `nc` are
laughable. Don't do that.

Amazon image: Add NVMe support to the initrd
This is required by the new c5.* instance types.

Note that this changes disk names from /dev/xvd* to
/dev/nvme0n*. Amazon Linux has a udev rule that calls a Python script
named "ec2nvme-nsid" to create compatibility symlinks. We could use
that, but it would mean adding Python to the AMI closure...

Eelco Dolstra 2701665904 Fetch all EC2 metadata / user data in the initrd

Eelco Dolstra 06731dfcae ec2: Don't use ephemeral disks for /nix unionfs
This is a regression introduced by merging the EBS and S3 images. The
EBS images had a special marker /.ebs to prevent the initrd from using
ephemeral storage for the unionfs, but this marker was missing in the
consolidated image.

The fix is to check the file ami-manifest-path on the metadata server
to see if we're an S3-based instance. This does require networking in
the initrd.

Issue #12613.

cransom user f10bead8fd Do not relocate /nix and /tmp to small disks on AWS
The default behavior with an m3.medium instance is to relocate
/nix and /tmp to /disk0 because an assumption is made that any
ephemeral disk is larger than the root volume.  Rather than make
that assumption, add a check to see if the disk is larger, and
only then relocate /nix and /tmp.

Eelco Dolstra aeb31b97ad Update AMI generator
The EBS and S3 (instance-store) AMIs are now created from the same
image. HVM instance-store AMIs are also generated.

Disk image generation has been factored out into a function
(nixos/lib/make-disk-image.nix) that can be used to build other kinds
of images.

William A. Kennington III aa5d6922c5 Revert "Set boot.loader.grub.configurationLimit to 1 for gce/azure/amazon images. Setting to 0 results in empty grub config."
The issue was that grub was not building the default entry which would
leave systems unbootable. This can now be safely reverted as the default
entry is being built once again.

This reverts commit fd1fb0403c.
