Reed Allman 35e5f81bc8 add docs for --net=host hackery (#1105)
I've found this to be extremely useful. Not that I expect anyone to be able to
find this document on their own accord considering the breadth of
documentation that we have, this can still be useful for linking to from slack
at least (what docs are really for, right?)

also the triggers doc stuck out as confusing considering all the triggers
stuff going on, I was unable to comprehend how exactly it was helpful other
than making people aware that openstack exists and they could build an
extension into fn for it if they want to, but this seems true of most things?
so, removed it, if anyone objects maybe we could improve it a little?

# Docker Configuration
To get the best performance, you'll want to ensure that Docker is configured properly. These are the environments known to produce the best results:
1. Linux 4.7 or newer with aufs or overlay2 module.
2. Ubuntu 16.04 LTS or newer with aufs or overlay2 module.
3. Docker 17.10 or newer to be available.
It is important to reconfigure host's Docker with this filesystem module. Thus, in your Docker start scripts you must do as following:
```
docker daemon [...] --storage-driver=overlay2
```
In case you are using Ubuntu, you can reconfigure Docker easily by updating `/etc/docker/daemon.json` and restarting Docker:
```json
{
"storage-driver": "overlay2"
}
```
