Enable HPKP for aus1
So, this seems to have been fallen through the cracks. A while ago I got asked to ask Mozilla how to get subdomains added to the HPKP list. I got the info and tried to move that forward in #tor-project but that failed. So, here is where we are
```
18:01 < GeKo> so i asked around a bit a while back wrt getting more tpo
subdomains in the static firefox pin list.
18:02 < GeKo> and the answer was basically to open a ticket on bugzilla
18:02 < GeKo> probably similar to
https://bugzilla.mozilla.org/show_bug.cgi?id=1219185
18:03 < GeKo> or maybe even better as a child bug to the pin all the things one:
https://bugzilla.mozilla.org/show_bug.cgi?id=1004350
18:03 < GeKo> i'd be especially interested in static pins for the updater related
subdomains
18:04 < GeKo> what's the process for getting this moved forward?
```
One thing to consider is that Google is deprecating HPKP and pushing for CT. Not sure how that influences our decision for supporting HPKP ourselves
