feat: `mysql` enhancements and query consolidation

[cofin]

This PR refactors much of the mysql collector to include more detail and consolidate overlapping queries.

Summary of Changes: Adds the following:

• schema_objects.sql: This file queries the information_schema for all objects that belong to a schema. This includes most objects such as Tables, Views, Events, Triggers and Constraints
• data_types.sql: This file counts the specific types data types of each table.
• table_details.sql: This file collects and aggregates details about tables
• users.sql: This consolidates all of the previous queries for user aggregate information
• config.sql: This exports all parameters and replaces several separate files.

• eventsbyschemas.sql: Consolidated into schema_objects
