Support app.settings from environment in Docker image

[jsommr]

There is currently no easy way to add app.settings when using the Docker image. One has to override postgrest.conf, which seems somewhat complicated. My current workaround is to create pre-request functions that fill in the needed app.settings.

Is there a chance that something like this could be implemented:

PGRST_APP_SETTINGS1=key=value
PGRST_APP_SETTINGS2=key=value
PGRST_APP_SETTINGSN=key=value

Where N goes to 9 or some other number depending on how many app settings one assumes people could need.

Hey @nerfpops,

Ah, I think Wolfgang already solved this one on #1691. Have you tried the latest nightly?

You should be able to do:

PGRST_APP_SETTINGS_key1=value1
PGRST_APP_SETTINGS_key2=value2

I'm using a nightly from this year so I'm sure it'll work. Thank you, @steve-chavez!
