feat: implement mock for S3Tables service

[felixscherz]

Hi, this is in regards to #8422.

I used scripts/scaffold.py to setup the s3tables service. I had to modify some URL patterns for the S3 service, as they overlap with s3tables.

Supported methods:

• create_table_bucket
• get_table_bucket
• list_table_buckets
• delete_table_bucket
• create_namespace
• delete_namespace
• list_namespaces
• create_table
• get_table
• list_tables
• delete_table
• update_metadata_location
• get_metadata_location
• rename_table
• delete_table_bucket_policy
• delete_table_policy
• get_table_bucket_maintenance_configuration
• get_table_bucket_policy
• get_table_maintenance_configuration
• get_table_maintenance_job_status
• get_table_policy
• put_table_bucket_maintenance_configuration
• put_table_bucket_policy
• put_table_maintenance_configuration
• put_table_policy

Currently working on supporting the new type of S3 buckets within the existing S3 backend so that data can be written to/read from S3 tables.
