Add SSO variables to configuration file, so they can be added to the environment files

[Sascha Schwarz]

Desired Behavior

We are using the docker version of netbox and SSO with a Okta backend.

We have to change configuration.py to get the authentication settings from the environment variables.

I think it would be much more convenient for all users if they can simply add the settings for SSO(at least for the integrations outlined in the netbox documentation) in the environment variables, instead of editing the configuration.py. Just like this is done for most other settings as well.

Contrast to Current Behavior

Currently only the basic REMOTE_AUTH settings can be set in the environment variables.

Required Changes

I suggest to change the file configurations.py and add the lines below to support at least the SSO integrations outlined in the documentation.

SOCIAL_AUTH_OKTA_OPENIDCONNECT_KEY = environ.get('SOCIAL_AUTH_OKTA_OPENIDCONNECT_KEY')
SOCIAL_AUTH_OKTA_OPENIDCONNECT_SECRET = environ.get('SOCIAL_AUTH_OKTA_OPENIDCONNECT_SECRET')
SOCIAL_AUTH_OKTA_OPENIDCONNECT_API_URL = environ.get('SOCIAL_AUTH_OKTA_OPENIDCONNECT_API_URL')
SOCIAL_AUTH_AZUREAD_OAUTH2_KEY = environ.get('SOCIAL_AUTH_AZUREAD_OAUTH2_KEY')
SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET = environ.get('SOCIAL_AUTH_AZUREAD_OAUTH2_SECRET')
