Parameter validation in methods and in frontend modules

[bschmalhofer]

Currently OTOBO is pretty basic with parameter checking. All checks are hardcoded. I think that it would be nice to have some declarative parameter checks. For the frontend modules this could also be done with a PreApplication module.

Candidates for parameter checking are:

• Types::Param, as part of Type::Tiny (@bschmalhofer : my favourite)
• Params::Validate
• Data::FormValidator
• Params::ValidationCompiler
• JSON::Schema::Modern (@bschmalhofer : another favourite, requires Type::Tiny)
• Specio
• something based on Tests2 pattern
