feat: Support optional installation extras for MCP server and class-generator

[myakove]

Summary

The package currently installs all components (core, MCP server, class-generator) together. Users should be able to install only the components they need.

Proposed Installation Options

Installation	Command	Components
Core only	pip install openshift-python-wrapper	ocp_resources, fake_kubernetes_client
Core + MCP	pip install openshift-python-wrapper[mcp]	Core + mcp_server
Core + Class Generator	pip install openshift-python-wrapper[class-generator]	Core + class_generator
All components	pip install openshift-python-wrapper[all]	Core + MCP + Class Generator

Dependency Analysis

Core dependencies (required for ocp_resources):

• jsonschema
• kubernetes
• packaging
• python-benedict
• python-simple-logger
• requests
• timeout-sampler
• xmltodict

Class-generator specific (NOT used by core):

• cloup - CLI framework
• colorlog - Colored logging
• deepdiff - Diff comparisons
• jinja2 - Template rendering
• pyhelper-utils - Shell command utilities
• rich - Rich console output
• ruff - Code formatting for generated files

MCP specific:

• fastmcp - MCP server framework

Implementation

[project.optional-dependencies]
class-generator = [
    "cloup>=3.0.5",
    "colorlog>=6.8.2",
    "deepdiff>=8.0.1",
    "jinja2>=3.1.4",
    "pyhelper-utils>=0.0.42",
    "rich>=13.9.2",
    "ruff>=0.6.9",
]
mcp = [
    "fastmcp>=2.10.4",
]
all = [
    "openshift-python-wrapper[mcp,class-generator]",
]

Benefits

1. Smaller default install - Core package goes from 16 dependencies to 8
2. Flexibility - Install only what you need
3. Reduced dependency conflicts - Fewer dependencies = fewer potential conflicts

Tasks

• Move class-generator dependencies to [class-generator] extra
• Move fastmcp to [mcp] extra
• Update [tool.hatch.build.targets.wheel] to conditionally include packages
• Update documentation with new installation options
• Update README with installation variants
