Defer import of system modules and Azure SDKs

[JacobCallahan]

Fixes:

• Resolve an issue where importing VmState in Robottelo could trigger errors due to the eager loading of all system provider modules and their heavy dependencies. This change allows VmState to be imported without pulling in unused provider SDKs.

Refactoring:

• Implement __getattr__ in wrapanapi/__init__.py and wrapanapi/systems/__init__.py to lazily import system classes (e.g., EC2System, VMWareSystem). This defers the loading of module dependencies until a specific system class is accessed.
• Introduce lazy importing for Azure SDK components within wrapanapi/systems/msazure.py. Azure dependencies are now loaded only when an Azure system or entity is instantiated, avoiding unnecessary module loading and potential import errors when the SDK is not present or needed.
• Adjust a multi-line expression in wrapanapi/systems/nuage.py for improved readability.

Configuration:

• Update ruff-pre-commit to version v0.15.0.
• Update pyupgrade to version v3.21.2.

Pull request overview

This PR refactors wrapanapi to avoid eagerly importing all provider system modules (and their heavy SDK dependencies) when importing convenience symbols like VmState, and introduces lazy loading for Azure SDK dependencies so Azure packages are only required when Azure functionality is actually used.

Changes:

• Add module-level __getattr__ lazy loaders in wrapanapi/__init__.py and wrapanapi/systems/__init__.py to defer provider system imports until accessed.
• Lazily import Azure SDK components in wrapanapi/systems/msazure.py via an _ensure_azure_imports() gate invoked during Azure object construction.
• Minor readability tweak in Nuage stats expression and bump pre-commit hook versions.
