OpenAPI handler doesn't preserve enum case

[Eldow]

Describe the bug
With the GraphQL handler, enum case is preserved, that's not the case with the openAPI handler.

I tried adding a naming convention transform to work around the issue, but it then breaks operations :

To Reproduce
Point to an openAPI datasource with lowercase enums.

"Animals":{"type":"string","enum":["fox","dog","cat"]}

WIth naming convention enum lowerCase off :
Everything works fine but the generated enums are uppercase.

With naming convention enum lowerCase on :

"message": "Variable \"$_v0_listAnimalsInput\" of required type \"ListAnimalsInput!\" was not provided.",

@ardatan You can assign this to me, I will have a look

@tvvignesh You can wait for the new OpenAPI handler implementation. I'll replace the existing fork of openapi-to-graphql with the new one

We are currently rewriting the OpenAPI handler and releasing it as newOpenapi
https://github.com/Urigo/graphql-mesh/blob/master/packages/handlers/new-openapi/yaml-config.graphql

In this new handler, we preserve enum cases as they are.
Closing this issue for now. Let us know if you have any more issues :)
Thanks
