Allow for self signed certificates

[KjellRanda]

I am running Grafana with a self signed certificate and my own certificate authority using https
Have to set "verify_ssl": false, and get the following messages:
/usr/lib/python3.11/site-packages/urllib3/connectionpool.py:1061: InsecureRequestWarning: Unverified HTTPS request is being made to host 'www.net.home'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/1.26.x/advanced-usage.html#ssl-warnings

Please provide the possibility to specify my root certificate as a certificate authority in the config file.
