* [BUG][PYTHON] Do not set Content-Type for GET, HEAD or DELETE requests The Python generator no longer sets a default `Content-Type` of `application/json` for `GET`, `HEAD` and `DELETE` requests. Having the `Content-Type` set for these requests was causing issues with other tools which insist that GET, HEAD and DELETE requests do not have a Content-Type (as per the OpenAPI 3 specification). An example of the problem that this commit fixes is when using [Prism][1] as a [validation proxy][2]. [Prism rejects any GET request that has a Content-Type][3]. Here is [an example of the problem manifesting itself][4]. To validate the fix in this commit: 1. Start with any OpenAPI3 spec e.g. the Petstore example at https://editor.swagger.io/ 2. Generate Python client code for the spec 3. Look at the generated `rest.py` e.g. in the [standard sample in this repo][5] and see that the `Content-Type` defaults to `application/json` for all HTTP methods (including `GET`, `HEAD` and `DELETE`), rather than there being no `Content-Type` for `GET`, `HEAD` and `DELETE`.

This commit fixes that bug and also includes the updated samples. Co-authored-by: William Cheng <wing328hk@gmail.com>
