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Existing tools.yaml configuration files are now in an outdated format.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pre-processing layer that automatically detects outdated configuration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
```

postgres-list-pg-settings docs 1 The "postgres-list-pg-settings" tool lists PostgreSQL run-time configuration settings.
/resources/tools/postgres-list-pg-settings

About

The postgres-list-pg-settings tool lists the configuration parameters for the postgres server, their current values, and related information. It's compatible with any of the following sources:

postgres-list-pg-settings lists detailed information as JSON for each setting. The tool takes the following input parameters:

  • setting_name (optional): A text to filter results by setting name. Default: ""
  • limit (optional): The maximum number of rows to return. Default: 50.

Example

kind: tools
name: list_indexes
type: postgres-list-pg-settings
source: postgres-source
description: |
  Lists configuration parameters for the postgres server ordered lexicographically, 
  with a default limit of 50 rows. It returns the parameter name, its current setting,
  unit of measurement, a short description, the source of the current setting (e.g.,
  default, configuration file, session), and whether a restart is required when the
  parameter value is changed."

The response is a json array with the following elements:

{
 "name": "Setting name",
 "current_value": "Current value of the setting",
 "unit": "Unit of the setting",
 "short_desc": "Short description of the setting",
 "source": "Source of the current value (e.g., default, configuration file, session)",
 "requires_restart": "Indicates if a server restart is required to apply a change ('Yes', 'No', or 'No (Reload sufficient)')"
}

Reference

field type required description
type string true Must be "postgres-list-pg-settings".
