feat: Argument spec implementation dszabo

[DonatSzabo]

Enhancement: Added argument spec and assert role spec validation to the bootloader role. Also wrote tests for it found in tests/tests_invalid_input.

Reason: Because it is a good addition to the linux-system-roles project.

Result: Successfully added it and prepared tests for it. I used AI during this implementation.

Summary by CodeRabbit

• New Features

  • Added comprehensive validation for bootloader configuration parameters, including kernel settings, timeout, passwords, reboot behavior, fact gathering, and secure logging.
  • Configuration parameters are now checked before bootloader changes are applied.

• Bug Fixes

  • Invalid values now produce clearer, type-specific validation errors.
  • Kernel settings must include a target kernel, preventing incomplete entries from being accepted.

• Tests

  • Added coverage for invalid parameter types, unsupported values, missing settings, and malformed kernel options.

📝 Walkthrough

Walkthrough

Changes

Adds an Ansible argument specification for bootloader parameters, runtime validation before configuration, and invalid-input tests for argument-spec and assertion failures.

Bootloader validation

Layer / File(s)	Summary
Define bootloader parameter contracts meta/argument_specs.yml	Defines bootloader_settings, kernel and option shapes, timeout, password, reboot, fact-gathering, and secure-logging parameters.
Validate parameters before configuration tasks/assert_role_vars.yml, tasks/main.yml	Validates timeout, password, kernel entries, and option values before configuration tasks run.
Test rejected parameter values tests/tests_invalid_input.yml	Tests argument-spec and runtime assertion failures, then clears test facts.

Suggested reviewers: spetrosi

Merge Risk: 🔵 Low · up to e744c

The bootloader validation tests may not reliably isolate repeated role invocations, which can obscure invalid-input behavior. This should be corrected or explicitly accepted before merge.
