Move custom nginx config to a different file

[flamingspaz]

Moving it to a different file allows us to add/mount our own custom configuration.

@flamingspaz i approved but didnt merge yet - im wondering: would this work for your configuration, if we had a location = / {...} with all the cruft, then an additional custom.conf for the proxy_pass location?

This would ensure all reqs have the correct HTTPS redirect / harder to mess up custom configs and disable https by mistake for example

from irc/slack chat:

s/custom.conf/bypass_proxy.conf/ is probably the best solution to make things clear

also: can comment out the CSP header (though if u dont ill do it) since its more of an example, but can break some apps "by default"

in fact, i just did it except for the CSP comment ;p

@yousef just looking for your review of my review then ill merge
