create a request object from an operation and list of parameter values

[karenetheridge]

given an operation (operationId or a path within the openapi document), and a list of (parameter => value) tuples, produce the corresponding Mojo::Message::Request object.

Optionally just produce the URI (skipping headers), e.g. for including in the "_links" portion of a HAL-like response.

Error if the operation does not exist, or any required parameters are not provided.

This would be handy in a test, say as $t->send_ok($operation => {$key => $value, $key => $value }) ! (How to send request bodies? Maybe ..., { json => $data } ?)

Don't forget there could be conflicts between parameter names of different types, so maybe just prefer path over query over header over cookie. And error if there are any required parameters that aren't provided.
