Add support for UEFI snapshots

[eroen]

The UEFI state is not returned in api responses.

Please assume I don't know how ansible modules work. I haven't actually run the
test suite, but uploading snapshots works fine with and without UEFI from a
playbook.

⚡ Recommended focus areas for review Parameter Validation The uefi parameter is appended to resource_create_param_keys unconditionally when url is provided, but the parameter is only documented as being considered in that scenario. Ensure the API gracefully ignores uefi=false (the default) when it is not applicable, or add explicit validation to skip the parameter when it would have no effect. self.resource_create_param_keys.append("uefi") Duplicate Description The new snapshot entry re-uses the description {{ vultr_resource_prefix }}_desc2, which is already assigned to the preceding snapshot. This may lead to unexpected behavior or test failures if descriptions must be unique. Consider using a distinct description such as {{ vultr_resource_prefix }}_desc2_uefi. - description: "{{ vultr_resource_prefix }}_desc2_uefi"

PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
General	Avoid sending default uefi value Only append "uefi" when the parameter is explicitly provided. This prevents sending the default False value when the user omits the argument, ensuring backward compatibility. plugins/modules/snapshot.py [173] -self.resource_create_param_keys.append("uefi") +if self.module.params.get("uefi") is not None: + self.resource_create_param_keys.append("uefi") Suggestion importance[1-10]: 8 __ Why: This is a critical suggestion that prevents breaking backward compatibility. The current code always sends uefi=false even when the parameter is omitted, which could change API behavior for existing users. The suggested fix ensures uefi is only sent when explicitly provided.
