Use swagger api for Add IDP Configuration

[cesnietor]

Updates AddIDPConfiguration.tsx to use swagger api.

Other changes:

• for some reason the consoleApi.ts file was not including the JSON type so I had to add the consumes parameter in the swagger yaml.

Test Steps

Configure your MinIO with an IDP as defined in here:

1. Clone repo https://github.com/minio/minio-iam-testing
2. Run:

# To use with Docker:
make docker-run

3. Go to UI -> Administrator/Identity/OpenID
4. Click on Create Configuration and fill in the following:

    config_url="http://localhost:5556/dex/.well-known/openid-configuration" \
    client_id="minio-client-app" \
    client_secret="minio-client-app-secret" \
    scopes="openid,groups,email,profile" \
    redirect_uri="http://127.0.0.1:10000/oauth_callback" \
    role_policy="consoleAdmin"

5. Click on Save once the required fields are set
6. Restart should be required
7. Restart and Refresh page
8. New Configuration should be listed
