Disable checkNewVersion

[nsklikas]

Bug Description

The treafik flag global.checknewversion defaults to true. The charm does not set this flag. This means that periodically traefik tries to check if there is a new version but it fails due to a missing ca cert.

I believe that this is unintentional and the checkNewVersion should be always set to false. Feel free to close this issue if that's not the case.

To Reproduce

Deploy traefik

Environment

juju

Relevant log output

level=warning msg="Error checking new version: Get \"https://update.traefik.io/repos/traefik/traefik/releases\": tls: failed to verify certificate: x509: certificate signed by unknown authority"

This should indeed be set to false.
