fix(async-queries): make global async. queries cookie SameSite option configurable

CONTRIBUTING.md

@@ -1323,6 +1323,7 @@ The following configuration settings are available for async queries (see config
 - `GLOBAL_ASYNC_QUERIES_REDIS_STREAM_LIMIT_FIREHOSE` - the maximum number of events for all users (FIFO eviction)
 - `GLOBAL_ASYNC_QUERIES_JWT_COOKIE_NAME` - the async query feature uses a [JWT](https://tools.ietf.org/html/rfc7519) cookie for authentication, this setting is the cookie's name
 - `GLOBAL_ASYNC_QUERIES_JWT_COOKIE_SECURE` - JWT cookie secure option
+- `GLOBAL_ASYNC_QUERIES_JWT_COOKIE_SAMESITE` - JWT cookie same site option
 - `GLOBAL_ASYNC_QUERIES_JWT_COOKIE_DOMAIN` - JWT cookie domain option ([see docs for set_cookie](https://tedboy.github.io/flask/interface_api.response_object.html#flask.Response.set_cookie))
 - `GLOBAL_ASYNC_QUERIES_JWT_SECRET` - JWT's use a secret key to sign and validate the contents. This value should be at least 32 bytes and have sufficient randomness for proper security
 - `GLOBAL_ASYNC_QUERIES_TRANSPORT` - available options: "polling" (HTTP, default), "ws" (WebSocket, requires running superset-websocket server)
