[BUG][DEPLOY] Cert manager unable to issue certificates

[stobias123]

Describe the bug
Cert manager is trying to issue certificates, but it appears to get errors when updating the certificate resource.

Error Detail.

E0731 22:10:10.006286       1 controller.go:131] cert-manager/controller/certificates "msg"="re-queuing item  due to error processing" "error"="Certificate.certmanager.k8s.io \"multicloud-ca-cert\" is invalid: metadata.managedFields.fieldsType: Invalid value: \"\": must be `FieldsV1`" "key"="open-cluster-management/multicloud-ca-cert"

I think #99 is caused by this.

To Reproduce
Deploy 4.5 on vsphere (behind firewall)
Install ACM

Expected behavior
A clear and concise description of what you expected to happen.

upgrading openshift and installing 2.0 fixed this issue.
