Yuan Teoh 293c1d6889 feat!: update configuration file v2 (#2369 )

This PR introduces a significant update to the Toolbox configuration
file format, which is one of the primary **breaking changes** required
for the implementation of the Advanced Control Plane.

# Summary of Changes
The configuration schema has been updated to enforce resource isolation
and facilitate atomic, incremental updates.
* Resource Isolation: Resource definitions are now separated into
individual blocks, using a distinct structure for each resource type
(Source, Tool, Toolset, etc.). This improves readability, management,
and auditing of configuration files.
* Field Name Modification: Internal field names have been modified to
align with declarative methodologies. Specifically, the configuration
now separates kind (general resource type, e.g., Source) from type
(specific implementation, e.g., Postgres).

# User Impact
Existing tools.yaml configuration files are now in an outdated format.
Users must eventually update their files to the new YAML format.

# Mitigation & Compatibility
Backward compatibility is maintained during this transition to ensure no
immediate user action is required for existing files.
* Immediate Backward Compatibility: The source code includes a
pre-processing layer that automatically detects outdated configuration
files (v1 format) and converts them to the new v2 format under the hood.
* [COMING SOON] Migration Support: The new toolbox migrate subcommand
will be introduced to allow users to automatically convert their old
configuration files to the latest format.

# Example
Example for config file v2:
```
kind: sources
name: my-pg-instance
type: cloud-sql-postgres
project: my-project
region: my-region
instance: my-instance
database: my_db
user: my_user
password: my_pass
---
kind: authServices
name: my-google-auth
type: google
clientId: testing-id
---
kind: tools
name: example_tool
type: postgres-sql
source: my-pg-instance
description: some description
statement: SELECT * FROM SQL_STATEMENT;
parameters:
- name: country
  type: string
  description: some description
---
kind: tools
name: example_tool_2
type: postgres-sql
source: my-pg-instance
description: returning the number one
statement: SELECT 1;
---
kind: toolsets
name: example_toolset
tools:
- example_tool
```

About

MySQL is a relational database management system (RDBMS) that stores and manages data. It's a popular choice for developers because of its reliability, performance, and ease of use.

Available Tools

mysql-sql Execute pre-defined prepared SQL queries in MySQL.
mysql-execute-sql Run parameterized SQL queries in MySQL.
mysql-list-active-queries List active queries in MySQL.
mysql-get-query-plan Provide information about how MySQL executes a SQL statement (EXPLAIN).
mysql-list-tables List tables in a MySQL database.
mysql-list-tables-missing-unique-indexes List tables in a MySQL database that do not have primary or unique indices.
mysql-list-table-fragmentation List table fragmentation in MySQL tables.

Requirements

Database User

This source only uses standard authentication. You will need to create a MySQL user to login to the database with.

Example

kind: sources
name: my-mysql-source
type: mysql
host: 127.0.0.1
port: 3306
database: my_db
user: ${USER_NAME}
password: ${PASSWORD}
# Optional TLS and other driver parameters. For example, enable preferred TLS:
# queryParams:
#     tls: preferred
queryTimeout: 30s # Optional: query timeout duration

{{< notice tip >}} Use environment variable replacement with the format ${ENV_NAME} instead of hardcoding your secrets into the configuration file. {{< /notice >}}

Reference

field	type	required	description
type	string	true	Must be "mysql".
host	string	true	IP address to connect to (e.g. "127.0.0.1").
port	string	true	Port to connect to (e.g. "3306").
database	string	true	Name of the MySQL database to connect to (e.g. "my_db").
user	string	true	Name of the MySQL user to connect as (e.g. "my-mysql-user").
password	string	true	Password of the MySQL user (e.g. "my-password").
queryTimeout	string	false	Maximum time to wait for query execution (e.g. "30s", "2m"). By default, no timeout is applied.
queryParams	map<string,string>	false	Arbitrary DSN parameters passed to the driver (e.g. `tls: preferred`, `charset: utf8mb4`). Useful for enabling TLS or other connection options.
