On first visit in firefox, must-staple certs (unlike chrome which ignores must-staple) always fail.
Investigating, it turns out, nginx does not fetch OCSP responses on reload or restart - https://trac.nginx.org/nginx/ticket/812 .
So, one has to prime the OCSP cache using curl requests. Alternately, one can use `openssl ocsp -noverify -no_nonce` and
then set `ssl_stapling_file`. Both approaches won't work if the OCSP servers are down and then we have to have some retry logic.
Also, the cache is per nginx worker, so I have no clue how many times one has to call curl. The `ssl_stapling_file` approach
requires some refresh logic as well. All very messy.
For the moment, do not set must-staple in the cert. Instead, check if the cert has a CSP URL and then enable
stapling in nginx accordingly.
can verify stapling using openssl s_client -connect hostname:443 -status
status_request is RFC6066. there is also status_request_v2 (RFC6961) but this is
not implemented even in openssl libs yet
had to move the ~ login/logout regexp inside. This is because of
https://www.ruby-forum.com/t/proxy-pass-location-inheritance/239135
What it says is that a regexp inside a matching location prefix is
given precedence regardless of how it appears in the file. This means
that the negative regexp got precedence over login|logout and thus
went into infinite redirect. By moving it to same level, the regexps
are considered in order.
Some notes on nginx location:
* First, it will match the prefixes (= and the /). If =, the matching stops.
If /xx then the longest match is "remembered"
* It will then match the regex inside the longest match. First match wins
* It will then match the rest of the regex locations. First match win
* If no regex matched, it will then do the remembered longest prefix

We removed httpPort with the assumption that docker allocated IPs
and kept them as long as the container is around. This turned out
to be not true because the IP changes on even container restart.
So we now allocate IPs statically. The iprange makes sure we don't
overlap with addons and other CI app or JupyterHub apps.

we can just use container IP instead of all this httpPort exporting magic.
this is also required for exposing httpPaths feature (we have to otherwise
have multiple httpPorts).
'setup' endpoint for setup/restore. we show the setup wizard.
'ip' endpoint is post activation. we show a splash screen here.
Also, the https://ip will not respond to any api calls anymore
(since this will leak the admin fqdn otherwise).
We should probably make this customizable at some point.
Fixes#739
* app certs set by user are always preferred
* If fallback, choose fallback certs. ignore others
* If LE, try to pick LE certs. Otherwise, provider fallback.
Fixes#724
