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Existing tools.yaml configuration files are now in an outdated format.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pre-processing layer that automatically detects outdated configuration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-upgrade-precheck docs 11 Perform a pre-check for a Cloud SQL for PostgreSQL major version upgrade.

The postgres-upgrade-precheck tool initiates a pre-check on a Cloud SQL for PostgreSQL instance to assess its readiness for a major version upgrade using the Cloud SQL Admin API. It helps identify potential incompatibilities or issues before starting the actual upgrade process.

{{< notice info >}} This tool uses a source of type cloud-sql-admin. {{< /notice >}}

Tool Inputs

Example

kind: tools
name: postgres-upgrade-precheck
type: postgres-upgrade-precheck
source: cloud-sql-admin-source
description: "Checks if a Cloud SQL PostgreSQL instance is ready for a major version upgrade to the specified target version."

Reference

field type required description
type string true Must be "postgres-upgrade-precheck".
source string true The name of the cloud-sql-admin source to use.
description string false A description of the tool.
parameter type required description
project string true The project ID containing the instance.
instance string true The name of the Cloud SQL instance to check.
targetDatabaseVersion string false The target PostgreSQL major version for the upgrade (e.g., POSTGRES_18). If not specified, defaults to the PostgreSQL 18.
