nixos/treewide: Move rename.nix imports to their respective modules
A centralized list for these renames is not good because:
- It breaks disabledModules for modules that have a rename defined
- Adding/removing renames for a module means having to find them in the
central file
- Merge conflicts due to multiple people editing the central file

bde525aaaf Add restore service for tarsnap archives
This service will never run automatically, but it encapsulates the
necessary logic and configuration to run a restore of the latest
archive, and allows to hook more specific logic, such as loading
a database dump, via `postStart`.

d462595600 Add support for tarsnap options -H and -L
A new option `explicitSymlinks` will set `-H` when creating an archive.
This option makes tarsnap follow any symlinks specified explicitly on
the commandline, but not any found inside the file tree.

A new option `followSymlinks` will set `-L` when creating an archive.
This option makes tarsnap follow any symlinks found anywhere in the file
tree instead of storing them as-is.

7a01badef5 nixos: tarsnap - allow keys for individual archives
Two concurrent tarsnap backups cannot be run at the same time with the
same keys - completely separate sets of keys must be generated for each
archive in this case, if you want backups to overlap.

This extends the archives attrset to support a 'keyfile' option, which
defaults to /root/tarsnap.key like the top-level attribute.

With this change, if you generate two keys with tarsnap-keygen(1) and
use each of those separately for each archive, you can backup
concurrently.

ec70f64ecd nixos: tarsnap - separate archive cachedirs
Tarsnap locks the cachedir during backup, meaning if you specify
multiple backups with a shared cache that might overlap (for example,
one backup may take an hour), secondary backups will fail. This isn't
very nice behavior for the obvious reasons.

This splits the cache dirs for each archive appropriately. Note that
this will require a rebuild of your archive caches (although if you were
only using one archive for your whole system, you can just move the
directory).

ad796f155b nixos: tarsnap - make systemd timer persistent
A machine may not always be active (or online!) when a backup timer
triggers, meaning backups can be missed - now we properly set the
tarsnap timer's Persistent option so systemd will run the command even
when the machine wasn't online at that exact time.

However, we also need to make sure that we can contact the tarsnap
server reliably before we start the backup. So, we attempt to ping the
access endpoint in a loop with a sleep, before continuing.

This fixes #8823.

1bdd12ed69 nixos: refactor tarsnap backup service module
Major changes
- Port to systemd timers: for each archive configuration is created a
  tarsnap@archive-name.timer which triggers the instanced service unit
- Rename the `config` option to `archives`

Minor/superficial improvements
- Restrict tarsnap service capabilities
- Use dirOf builtin
- Set executable bit for owner of tarsnap cache directory
- Set IOSchedulingClass to idle
- Humanize numbers when printing stats
- Rewrite most option descriptions
- Simplify assertion

9242ed1fe2 nixos: refactor tarsnap module
The Tarsnap module is now far more flexible, allowing individual
archives with individual options to be specified at will, allowing
granular backup schedules, etc.

29027fd1e1 Rewrite ‘with pkgs.lib’ -> ‘with lib’
Using pkgs.lib on the spine of module evaluation is problematic
because the pkgs argument depends on the result of module
evaluation. To prevent an infinite recursion, pkgs and some of the
modules are evaluated twice, which is inefficient. Using ‘with lib’
prevents this problem.
