Query for http verbs that can be added to swagger spec if request verb condition is missing

[anil614sagar]

Resources that doesn't have http verb defined with them in apigee proxy flow fails to show up in swagger spec 2.0. Swagger 2.0 spec expects user to define http verbs under a path. But, Apigee Proxy can be created without a verb with just path condition.

If verb is missing, ideally tool should query user which http verbs to add to swagger spec or by default add GET verb to same.
