Draft: set the install job timeout to 45 minutes

Issue: #54 (closed)

The helm install command has configurable timeout, by default 45m. While the job waiting for completion has a hardcoded timeout of 600s (10 minutes).

Ideally we should make this configurable, but I need to understand better if I have access to the cern_chart_user_values at this stage, and it would require extra code for decoding the values, selecting the helm_install_timeout, etc.
