    - #### create

          static OAuth2Auth create(Vertx vertx,
                                   JsonObject config)

      Create a OAuth2Auth provider for Keycloak
      Parameters:
        `config` - the json config file exported from Keycloak admin console

    - #### create

          static OAuth2Auth create(Vertx vertx,
                                   OAuth2FlowType flow,
                                   JsonObject config)

      Create a OAuth2Auth provider for Keycloak
      Parameters:
        `flow` - the oauth2 flow to use
        `config` - the json config file exported from Keycloak admin console

    - #### create

          static OAuth2Auth create(Vertx vertx,
                                   JsonObject config,
                                   HttpClientOptions httpClientOptions)

      Create a OAuth2Auth provider for Keycloak
      Parameters:
        `config` - the json config file exported from Keycloak admin console
        `httpClientOptions` - custom http client options

    - #### create

          static OAuth2Auth create(Vertx vertx,
                                   OAuth2FlowType flow,
                                   JsonObject config,
                                   HttpClientOptions httpClientOptions)

      Create a OAuth2Auth provider for Keycloak
      Parameters:
        `flow` - the oauth2 flow to use
        `config` - the json config file exported from Keycloak admin console
        `httpClientOptions` - custom http client options

    - #### discover

          static void discover(Vertx vertx,
                               OAuth2ClientOptions config,
                               Handler<AsyncResult<OAuth2Auth>> handler)

      Create a OAuth2Auth provider for OpenID Connect Discovery. The discovery will use the default site in the configuration options and attempt to load the well known descriptor. If a site is provided (for example when running on a custom instance) that site will be used to do the lookup.

      If the discovered config includes a json web key url, it will be also fetched and the JWKs will be loaded into the OAuth provider so tokens can be decoded.

      Specified by:
        `discover` in interface `OpenIDConnectAuth`
      Parameters:
        `vertx` - the vertx instance
        `config` - the initial config
        `handler` - the instantiated Oauth2 provider instance handler
