A secret key generated by the nixos module was misspelled, which could
possibly impact the security of session cookies.
To recover from this situation we will wipe all security keys that were
previously generated by the NixOS module, when the misspelled one is
found. This will result in all session cookies being invalidated. This
is confirmed by the wordpress documentation:
> You can change these at any point in time to invalidate all existing
> cookies. This does mean that all users will have to login again.

Meanwhile this issue shouldn't be too grave, since the salting function
of wordpress will rely on the concatenation of both the user-provided
and automatically generated values, that are stored in the database.
> Secret keys are located in two places: in the database and in the
> wp-config.php file. The secret key in the database is randomly
> generated and will be appended to the secret keys in wp-config.php.

Assert that the PostgreSQL version being deployed is the one used
upstream. Allow the user to override this assertion, since it's not
always possible or preferable to use the recommended one.
Instead of requiring the user to bundle the certificate and private
key into a single file, provide separate options for them. This is
more in line with most other modules.
`install` copies the files before setting their mode, so there could
be a breif window where the secrets are readable by other users
without a strict umask.
Feeding `psql` the password on the command line leaks it through the
`psql` process' `/proc/<pid>/cmdline` file. Using `echo` to put the
command in a file and then feeding `psql` the file should work around
this, since `echo` is a bash builtin and thus shouldn't spawn a new
process.
Using `replace-literal` to insert secrets leaks the secrets through
the `replace-literal` process' `/proc/<pid>/cmdline`
file. `replace-secret` solves this by reading the secret straight from
the file instead, which also simplifies the code a bit.

This reverts commit d9e18f4e7f.
This change is broken, since it doesn't configure the proper database
username in keycloak when provisioning a local database with a custom
username. Its intended behavior is also potentially confusing and
dangerous, so rather than fixing it, let's revert to the old one.
Bash doesn't handle subshell errors properly if the result is used as
input to a command. To cause the services to fail when the files can't
be read, we need to assign the value to a variable, then export it
separately.
As the only consequence of isSystemUser is that if the uid is null then
it's allocated below 500, if a user has uid = something below 500 then
we don't require isSystemUser to be set.

This adds two options to the nextcloud module, with the aim of allowing
the entirety of `config.php` to be set declaratively:
1. `services.nextcloud.extraOptions`, which takes free-form options
given as an attribute set, and reads them in via json from the php
side (which lets us prevent syntax errors in php, if not key errors –
given the full length of nextcloud's potential options, I don't think
specifying them all via Nix is a viable option)
2. `services.nextcloud.secretFile`, which takes a path to a json file
specifying options which a user may want to keep secret and not add
to their nix store; this file is read in the same way on startup by
php, and may even overwrite options set in some other way.
This allows for shared hledger installations, where the web interface is
available via network and multiple user share a SSH access to the
hledger user.
Also added `--serve` to the CLI options, as hledger-web tries to open a
webbrowser otherwise:
hledger-web: xdg-open: rawSystem: runInteractiveProcess: exec: does not
exist (No such file or directory)
