[Python] Selecting Endpoint for the README example

Description

Is there a way to select which endpoint is used to generate the example for the README?

It looks like the current method sorts by tag and operationID and selects the first one to generate an example for.

Given the following paths and tags (spec kept minimal to illustrate issue and is not valid):

paths:
  "/z1/":
    get:
      operationId: z1
      tags:
        - Z
  "/z2/":
    get:
      operationId: z2
      tags:
        - Z
  "/a2":
    get:
      operationId: a2
      tags:
        - A
  "/a1/":
    get:
      operationId: a1
      tags:
        - A

The generated README will contain an example similar to:

from __future__ import print_function
import time
import swagger_api
from swagger_api.rest import ApiException
from pprint import pprint

# create an instance of the API class
api_instance = swagger_api.AApi()

try:
    # Check if server is responding to queries.
    api_instance.a1()
except ApiException as e:
    print("Exception when calling AdminApi->ping: %s\n" % e)

What I want instead is for the example to use ZApi().z2().

Swagger-codegen version

2.3.0

Swagger declaration file content or url

https://api.swaggerhub.com/apis/cyledoux/cythereal-magic-api/1/swagger.json

Command line used for generation

docker run --rm -v $HOME/clients:/local swaggerapi/swagger-codegen-cli generate -i https://api.swaggerhub.com/apis/cyledoux/cythereal-magic-api/1/swagger.json -l python -o /local/clients/python --config=/local/config/python.json

Start with the supplied Docker generation command and trace how the Python README example chooses and sorts endpoints. Confirm how configuration is passed to the generator, then define completion as allowing the example to select the requested ZApi().z2() endpoint instead of the current first endpoint.
