[chectl] failed to install che with helm if k8s cluster has stable cert-manager

[sleshchenko]

Describe the bug

[chectl] failed to install che with helm if k8s cluster has stable cert-manager.

The easy solution I see - just upgrade cert-manager chectl uses to the stable one https://github.com/che-incubator/chectl/blob/master/installers/cert-manager.yml

Che version

• latest
• nightly
• other: please specify

Steps to reproduce

1. Run minikube.
2. Install the stable cert-manager, like kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v1.0.4/cert-manager.yaml <- one which is used by devworkspace operator.
3. Try to install Che with helm chart.

Expected behavior

Che is installed.

Actual behavoir

> chectl server:deploy -n che --multiuser --platform=minikube --installer=helm      % 16:57:16
