[Feature Request] Handle region-specific configurations as region parameters

[avouacr]

Right now, region-specific configurations (e.g. proxy adresses, certificates..) are applied through init scripts run at services startup. These settings should be instead passed as parameters of the region, so that they can be directly injected through the chart of the service.

This change would be especially useful when working with an Onyxia instance not open to the internet, as it is not possible/easy to fetch the region init script.. which precisely configures regional proxies/certificates settings (chicken-egg problem).

How should it be handle in the pojo region? I mean which property shoud we add in https://github.com/InseeFrLab/onyxia-api/blob/be4705924e3d073b38745e31349aeb7e0af0acdb/onyxia-model/src/main/java/fr/insee/onyxia/model/region/Region.java

For example at root of region should we add:

network : { httpProxy: someValue, httpsProxy: someValue, noProxy someValue],
certificates : {authorities: [ "linktoAn AUthorities", "otherLink"]

just to keep trace :
images-datascience could be build as root with var_env that run script to delete sudo right.
or
images-datascience could be build as non root with var_env giving sudo right.

In this case to allow certificate injection when non root we could think about giving:

onyxia ALL(ALL:ALL) NOPASSWD:/usr/sbin/update-ca-certificates

As the PR is merge the next steps are modifying the charts and the images datascience
https://github.com/InseeFrLab/onyxia-api/blob/master/docs/region-configuration.md#proxyinjection-properties
https://github.com/InseeFrLab/onyxia-api/blob/master/docs/region-configuration.md#packagerepositoryinjection-properties
https://github.com/InseeFrLab/onyxia-api/blob/master/docs/region-configuration.md#certificateauthorityinjection-properties

charts and docker images-datascience it seems

[alexisdondon]

We need before update the ui to handle this new parameters InseeFrLab/onyxia#409

[alexisdondon]

This is possible from release 2.2.26 of onyxia-web and release v0.17 of onyxia-api

We could try the injection in helm charts catalogs
