Enum of type integer is not supported by OpenApiParser

[stupedvivu]

Issue:
When OpenApiParser tries to parse a Swagger 2.0 OpenAPI definition that includes an enum parameter of type integer, it does not return the function associated with that parameter. While debugging the OpenApiParser.GetFunctions() code, I found that the function is marked as not supported, with the reason: "Unsupported enum type (int)"

Attaching sample swagger definition -
