dashboard: allow disabling grafana api ssl verify

When using an untrusted TLS certificate (like self-signed) on grafana
then the grafana dashboards update subcommand will fail.
One solution could be to trust the TLS certificate.
The other one is to disable the TLS verification on the grafana API.

Closes: #5324
