Contributions summary:Abhisek implemented enhancements and resolved issues related to graceful shutdown functionality in the Presto query engine. They focused on supporting the shutdown of coordinator nodes using the `/info/state` endpoint, ensuring proper query and task completion during the shutdown process. They also added custom JSON serializers for `DataSize` and `Duration` for displaying well-formatted values in the UI, and modified the `SHOW CREATE TABLE` SQL output to correctly quote column names. The user also contributed to multi-coordinator support for query and resource group info.
