Setting up connection for no verify and client certificate cases

[lpenet]

To test:

• build a kit with this branch
  • edit make-studio-package.sh to set the API_CLIENT_VERSION to this branch name
  • smtg like make && NOGEO=1 NOGEOIP=1 ./packagers/studio/make-studio-package.sh 11.0.0-20220410 ~/dss-releases
• install it
• test in a notebook (without encrypted RPC)
• enable encrypted RPC: ./bin/dssadmin install-encrypted-rpc
• test in a notebook

Simple code like:

import dataiku
import mlflow
import os

client = dataiku.api_client()
project = client.get_project("POUET")
mf = project.get_managed_folder("w6adRQEB")

#os.environ["MLFLOW_TRACKING_INSECURE_TLS"]="true"

project.setup_mlflow(managed_folder=mf)

with mlflow.start_run():
        mlflow.log_param("alpha", 1)
        mlflow.log_param("l1_ratio", 2)
        mlflow.log_metric("rmse", 3)
        mlflow.log_metric("r2", 4)
        mlflow.log_metric("mae", 5)

should be ok.

This pull request has been linked to Shortcut Story #85243: MLFlow integration does not work if the DSSClient uses a custom certificate or has disabled certificate verification.

Tested and LGTM

OK with custom certificate

NOK if custom certificate and disable insecure_TLS
