Updated client.py to conform to new openapi generated api_client.py

I removed the default Content-Type: */* as kubernetes does not seem to like that.

Example:

curl -k -x socks5://localhost:9090/ \
     --header "Accept: application/json" \
     --header "Content-Type: */*" \
     https://xxxx:6443/version
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "406: Not Acceptable\n\nAvailable representations: ",
  "reason": "NotAcceptable",
  "details": {},
  "code": 406
}

Unsure how that worked before, but simply not setting a content type worked.
