I have a nixops network where I deploy containers using the `container`
backend which uses `nixos-container` intenrally to deploy several
containers to a certain host.
During that time I removed and added new containers and while trying to
deploy those to a different host I realized that it isn't guaranteed
that each container gets the same IP address which is a problem as some
parts of the deployment need to know which container is using which IP
(i.e. to configure port forwarding on the host).
With this change you can specify the container's IP like this (and don't
have to use the arbitrarily used 10.233.0.0/16 subnet):
```
$ nixos-container create test --config-file test-container.nix \
--local-address 10.235.1.2 --host-address 10.235.1.1
```
This is to make sure that we get different ETag values whenever we
switch to a different store path but with the same file contents.
I've checked this against the old behaviour without the patch and it
fails as expected.

This makes sure that when a user hasn't set a Prometheus option it
won't show up in the prometheus.yml configuration file. This results
in smaller and easier to understand configuration files.
We previously filtered out the `_module` attribute in a NixOS
configuration by filtering it using the option's `apply` function.
This meant that every option that had a submodule type needed to have
this apply function. Adding this function is easy to forget thus this
mechanism is error prone.
We now recursively filter out the `_module` attributes at the place we
construct the Prometheus configuration file. Since we now do the filtering
centrally we don't have to do it per option making it less prone to errors.
This results in a smaller prometheus.yml config file.
It also allows us to use the same options for both prometheus-1 and
prometheus-2 since the new options for prometheus-2 default to null
and will be filtered out if they are not set.
Get these from upstream tox-node package instead.
This is likely to cause less maintenance overhead over time and
following upstream bootstrap node changes is automated.
This adds the following new packages:
+ elasticsearch7
+ elasticsearch7-oss
+ logstash7
+ logstash7-oss
+ kibana7
+ kibana7-oss
+ filebeat7
+ heartbeat7
+ metricbeat7
+ packetbeat7
+ journalbeat7
The default major version of the ELK stack stays at 6. We should
probably set it to 7 in a next commit.
