It looks like some nix update has broken our current Terraform setup.
The Google provider plugin has changed its reported version to 0.0.0;
poking at my local nix store seems to indicate we actually get 3.15, but
🤷.
This PR also reverts the infra part of #6400 so we get back to master ==
reality.

Nix now requires -L, I’ve gone ahead and just normalized everything to
use -sfL which we were already using in one place.

We have seen the following error message crop up a couple times
recently:
```
FATAL: could not create shared memory segment: No space left on device
DETAIL: Failed system call was shmget(key=5432001, size=56, 03600).
HINT: This error does *not* mean that you have run out of disk space.
It occurs either if all available shared memory IDs have been taken, in
which case you need to raise the SHMMNI parameter in your kernel, or
because the system's overall limit for shared memory has been reached.
The PostgreSQL documentation contains more information about shared
memory configuration.
child process exited with exit code 1
```
Based on [the PostgreSQL
documentation](https://www.postgresql.org/docs/12/kernel-resources.html),
this should fix it.

set up macOS nodes
This PR documents how to create and manage macOS CI nodes. Because macOS
is not supported by our current cloud providers, these instructions are
geared towards creating VMs on physical machines we would need to host
and manage ourselves, i.e. these notes are mostly targeted at Ed.
