This is useful to force on-interactive mode with automatic key selection. In unit tests this is necessary. When debugging a test on a real terminal interactive mode is not desired
This is basically
<af7ce9b8ed>,
but with support for deploying locally.
This failed to install secrets to `/var/lib/sops-nix`. That's because
our `LocalHost` didn't have support for sudo yet. I fixed that.
Now the user can pass `--build-host local`, to select the local machine as a build host, in which case no ssh is used.
This means the admin machine does not necessarily have ssh set up to itself, which was confusing for many users.
Also this makes it easier to re-use a well configured nix remote build setup which is only available on the local machine. Eg if `--build-host local` nix' defaults for remote builds on that machine will be utilized.
pathlib.Path("git+file:///foo").resolve() might resolve to urls like
PosixPath('/home/joerg/work/clan/clan-core/git+file:/foo'). If those
then actually exist, this can have weird behavior. We should in general
avoid changing directories for everything except for subprocess.run.
This now gives a clearer error than:

When not being in a flake.
Motivation: updating a machine fails, if it depends on a private github repo, as the remote will likely not be authenticated.
This adds a new flag `--fetch-local` to `clan machines update` which fetches all flake inputs prior to building, then uploads them to the build-host.
This also adds a new error message, when flake inputs could not fetched, to hint the user to use `--fetch-local`
Fix clan template creation when already in a flake.
Currently we already fail with very clear and descriptive error when
trying to evaluate the template of the flake we are in:
```
Failed to select template 'flake-parts' from flake '/tmp/superclan' (via attribute path: /tmp/superclan#clanInternals.templates.clan."flake-parts")
```
This is undesired behavior.
When we are trying to create a clan with `clan flakes create`.
We can't rely on the fact that the flake we are currently in exports flake templates.
Now we *try* to evaluate the flake we are in upon creation.
If there are no clan templates available, we now will fall back to
builtin templates.
Closes: #4472
Allow `clan templates list` to function outside a clan.
Currently when bootstrapping a clan and trying to list the templates
it fails as follows:
```

With the change we get the following output:
```
Available 'clan' templates
├── <builtin>
│ ├── default: Initialize a new clan flake
│ ├── flake-parts: Flake-parts
│ └── minimal: for clans managed via (G)UI
Available 'disko' templates
├── <builtin>
│ └── single-disk: A simple ext4 disk with a single partition
Available 'machine' templates
├── <builtin>
│ ├── flash-installer: Initialize a new flash-installer machine
│ └── new-machine: Initialize a new machine
```
Allowing to check for available templates without needing to have a
clan, which improves the bootstrapping experience.
