Reason/Context

It would be very useful when working on docs/code generators to have a set of helper functions that let you easily determine if there is or not a specific component added to the components section of the AsyncAPI document and if it has any data. These components are not required and it is not required to have any data in them, so someone can add an empty object for example.

Many models already have useful functions like hasDescription.

Description
