Actually ```requests.delete``` function send internally ```DELETE``` as ```command/request```. Our stub servers are using ```BaseHTTPRequestHandler``` to handle HTTP requests. ```BaseHTTPRequestHandler``` parses the request and the headers, and then calls a function specific to the request type.  Specifically, a request ```DELETE``` will be handled by a method ```do_DELETE()```.
The same thing is happening in all the stub servers.

Anyway i have disabled the pylint waring.
