Pass multiple IDP config to console

[donatello]

Description

This change passes sending configuration of all configured IDPs to console via a struct.

This change only changes the method of passing configuration to console and passes all enabled IDPs to console - further work is needed for integrating multiple IDPs in the web UI.

Motivation and Context

This change allows us to integrate multiple IDPs in the web console in subsequent changes.

How to test this PR?

Existing functionality should be preserved - i.e. a single IDP should continue to work as-is with this change.

Run make podman-run from https://github.com/minio/minio-iam-testing to start testing IDP services.

Start minio with console on port 10000.

# Configure IDP as claim based provider (needs latest mc at time of writing)
$ mc admin idp set myminio openid     config_url="http://localhost:5557/dex/.well-known/openid-configuration"     client_id="minio-client-app-2"     client_secret="minio-client-app-secret-2"     scopes="openid,groups"     redirect_uri="http://127.0.0.1:10000/oauth_callback"     display_name="Login via dex2"     role_policy='' claim_name=groups

Now attempt to login normally via console (dillon@example.io and dillon as password).
