feat: Add allowed_operations init parameter to OpenAPITool

[vblagoje]

Why:

Introduces operation filtering in OpenAPITool to refine tools registration for LLM usage. OpenAPI specs have sometimes hundreds of operations making it unfeasible for LLM tools registration. This change allows users to register only a subset of operations from OpenAPI spec and more importantly makes long specs usable in OpenAPITool.

What:

• Added allowed_operations parameter in OpenAPITool to specify which API operations (tools) to register with LLMs.
• Expanded schema converters with an additional parameter to filter operations.

How can it be used:

openapi_tool = OpenAPITool(
    generator_api=LLMProvider.OPENAI,
    spec='path/to/your/spec.json',
    allowed_operations=['specificOperationId']
)

How did you test it:

• Unit tests for new logic in schema converters and operation filtering.
• Integration tests for OpenAPI client configuration with allowed_operations.
• Manual testing with sample configurations.

Notes for the reviewer:

• Verify operation filtering logic across all LLM providers.
• Review linter configuration adjustments.
• Consider additional edge cases for testing.
