[Console Monaco migration] Add support for url param values with whitespaces

[yuliacech]

The Monaco based editor is incorrectly parsing the url of the request when a url parameter has whitespaces in it. For example the request GET _search?q="rocky mountain" should work correctly.
The editor currently returns the following error

{
        "type": "query_shard_exception",
        "reason": """Failed to parse query ["rocky]""",
        "index_uuid": "fkj8LetvQbaZNlksv0okSw",
        "index": ".internal.alerts-ml.anomaly-detection-health.alerts-default-000001"
      },
