[jsafrane]

And adjust CSI snapshot operator memory request. Measured in https://openshift-release.apps.ci.l2s4.p1.openshiftapps.com/releasestream/4.7.0-0.nightly/release/4.7.0-0.nightly-2020-12-04-013308:

• The operator took 63MiB for most of the CI run: container_memory_max_usage_bytes{container="csi-snapshot-controller-operator",..., pod="csi-snapshot-controller-operator-8555964b44-lzsxd"} 66138112
• The webhook took 17 MiB for most of the CI run: container_memory_max_usage_bytes{container="webhook", ..., pod="csi-snapshot-webhook-f7bb59b75-8wqcq"} 18132992

For the record, snapshot-controller memory requirement is OK.
