Changes

Generic OAuth2 for USTC CAS

Changes to assets/runtime/config/gitlabhq/gitlab.yml:

- { name: 'oauth2_generic',
    app_id: '{{OAUTH2_GENERIC_USTC_APP_ID}}',
    app_secret: '{{OAUTH2_GENERIC_USTC_APP_SECRET}}',
    label: '{{OAUTH2_GENERIC_USTC_LABEL}}',
    args: {
    client_options: {
        site: '{{OAUTH2_GENERIC_USTC_CLIENT_SITE}}',
        user_info_url: '{{OAUTH2_GENERIC_USTC_CLIENT_USER_INFO_URL}}',
        authorize_url: '{{OAUTH2_GENERIC_USTC_CLIENT_AUTHORIZE_URL}}',
        token_url: '{{OAUTH2_GENERIC_USTC_CLIENT_TOKEN_URL}}',
    },
    authorize_params: {
        scope: "snsapi_userinfo",
        appid: {{OAUTH2_GENERIC_USTC_APP_ID}},
    },
    token_params: {
        appid: {{OAUTH2_GENERIC_USTC_APP_ID}},
        secret: '{{OAUTH2_GENERIC_USTC_APP_SECRET}}',
    },
    strategy_class: "OmniAuth::Strategies::OAuth2Generic",
    user_response_structure: {
        attributes: {},
        id_path: '{{OAUTH2_GENERIC_USTC_ID_PATH}}' } } }

Changes to assets/runtime/functions (gitlab_configure_oauth_azure_ad_v2 is replaced by gitlab_configure_oauth2_generic_ustc):

gitlab_configure_oauth2_generic_ustc() {
  if [[ -n ${OAUTH2_GENERIC_USTC_APP_ID} && \
        -n ${OAUTH2_GENERIC_USTC_APP_SECRET} ]]; then
    echo "Configuring gitlab::oauth::generic..."
    OAUTH_ENABLED=${OAUTH_ENABLED:-true}
    update_template ${GITLAB_CONFIG} \
    OAUTH2_GENERIC_USTC_APP_ID \
    OAUTH2_GENERIC_USTC_APP_SECRET \
    OAUTH2_GENERIC_USTC_LABEL \
    OAUTH2_GENERIC_USTC_CLIENT_SITE \
    OAUTH2_GENERIC_USTC_CLIENT_USER_INFO_URL \
    OAUTH2_GENERIC_USTC_CLIENT_AUTHORIZE_URL \
    OAUTH2_GENERIC_USTC_CLIENT_TOKEN_URL \
    OAUTH2_GENERIC_USTC_ID_PATH
  else
      exec_as_git sed -i "/name: 'oauth2_generic'/,/{{OAUTH2_GENERIC_USTC_ID_PATH}}/d" ${GITLAB_CONFIG}
  fi
}

gitlab_configure_oauth2_generic is commented out.

user_info_url (env OAUTH2_GENERIC_USTC_CLIENT_USER_INFO_URL) should be pointed to the container of https://github.com/ustclug/userinfo-proxy/.
