nixos/taskserver: Introduce an extraConfig option
This is simply to add configuration lines to the generated configuration
file. The reason why I didn't went for an attribute set is that the
taskdrc file format doesn't map very well on Nix attributes, for example
the following can be set in taskdrc:

server = somestring
server.key = anotherstring

In order to use a Nix attribute set for that, it would be way too
complicated, for example if we want to represent the mentioned example
we'd have to do something like this:

{ server._top = somestring;
  server.key = anotherstring;
}

Of course, this would work as well but nothing is more simple than just
appending raw strings.

nixos/taskserver: Allow to specify expiration/bits
At least this should allow for some customisation of how the
certificates and keys are created. We now have two sub-namespaces within
PKI so it should be more clear which options you have to set if you want
to either manage your own CA or let the module create it automatically.

nixos/taskserver: Silence certtool everywhere
We only print the output whenever there is an error, otherwise let's
shut it up because it only shows information the user can gather through
other means. For example by invoking certtool manually, or by just
looking at private key files (the whole blurb it's outputting is in
there as well).

nixos/taskserver: Add a command to reload service
Unfortunately we don't have a better way to check whether the reload has
been done successfully, but at least we now *can* reload it without
figuring out the exact signal to send to the process.

Note that on reload, Taskserver will not reload the CRL file. For that
to work, a full restart needs to be done.

nixos/taskserver: Generate a cert revocation list
If we want to revoke client certificates and want the server to actually
notice the revocation, we need to have a valid certificate revocation
list.

Right now the expiration_days is set to 10 years, but that's merely to
actually get certtool to actually generate the CRL without trying to
prompt for user input.

nixos/taskserver: Constrain server cert perms
It doesn't do much harm to make the server certificate world readable,
because even though it's not accessible anymore via the file system,
someone can still get it by simply doing a TLS handshake with the
server.

So this is solely for consistency.

nixos/taskserver: Handle declarative conf via JSON
We now no longer have the stupid --service-helper option, which silences
messages about already existing organisations, users or groups.

Instead of that option, we now have a new subcommand called
"process-json", which accepts a JSON file directly from the specified
NixOS module options and creates/deletes the users accordingly.

Note that this still has a two issues left to solve in this area:

 * Deletion is not supported yet.
 * If a user is created imperatively, the next run of process-json will
   delete it once deletion is supported.

So we need to implement deletion and a way to mark organisations, users
and groups as "imperatively managed".

nixos/taskserver: Rename .pki options
We're now using .pki.server.* and .pki.ca.* so that it's entirely clear
what these keys/certificates are for. For example we had just .pki.key
before, which doesn't really tell very much about what it's for except
if you look at the option description.

nixos/taskserver: Improve doc for PKI options

nixos/taskserver: Move .pki.fqdn to .fqdn
It's not necessarily related to the PKI options, because this is also
used for setting the server address on the Taskwarrior client.

So if someone doesn't have his/her own certificates from another CA, all
options that need to be adjusted are in .pki. And if someone doesn't
want to bother with getting certificates from another CA, (s)he just
doesn't set anything in .pki.

nixos/taskserver: Rename .server options to .pki
After moving out the PKI-unrelated options, let's name this a bit more
appropriate, so we can finally get rid of the taskserver.server thing.

This also moves taskserver.caCert to taskserver.pki.caCert, because that
clearly belongs to the PKI options.

nixos/taskserver: Rename server.{host,port}
Having an option called services.taskserver.server.host is quite
confusing because we already have "server" in the service name, so let's
first get rid of the listening options before we rename the rest of the
options in that .server attribute.

nixos/taskserver: Rewrite helper-tool in Python
In the comments of the pull request @nbp wrote:

"Why is it implemented in 3 different languages: Nix, Bash and C?"

And he's right, it doesn't make sense, because we were using C as a
runuser replacement and used Nix to generate the shellscript
boilerplates.

Writing this in Python gets rid of all of this and we also don't need
the boilerplate as well, because we're using Click to handle all the
command line stuff.

Note that this currently is a 1:1 implementation of what we had before.

nixos/taskserver: Remove client.cert option
The option is solely for debugging purposes (particularly the unit tests
of the project itself) and doesn't make sense to include it in the NixOS
module options.

If people want to use this, we might want to introduce another option so
that we can insert arbitrary configuration lines.

nixos/taskserver: Rename client.{allow,deny}
These values match against the client IDs only, so let's rename it to
something that actually reflects that. Having client.cert in the same
namespace also could lead to confusion, because the client.cert setting
is for the *debugging* client only.

nixos/taskserver: Fix type/description for ciphers
Referring to the GnuTLS documentation isn't very nice if the user has to
use a search engine to find that documentation. So let's directly link
to it.

The type was "str" before, but it's actually a colon-separated string,
so if we set options in multiple modules, the result is one concatenated
string.

I know there is types.envVar, which does the same as separatedString ":"
but I found that it could confuse the reader of the Taskserver module.

nixos/taskserver: Rename nixos-taskdctl
Using nixos-taskserver is more verbose but less cryptic and I think it
fits the purpose better because it can't be confused to be a wrapper
around the taskdctl command from the upstream project as
nixos-taskserver shares no commonalities with it.
