[occm] include cloudConfigContents in DaemonSet checksum annotation

When cloud config is supplied via cloudConfigContents rather than the
structured cloudConfig values, changes to it do not alter the checksum
annotation on the DaemonSet pod template. Pods are not restarted after
credential rotation or endpoint changes.

Fixes #3030
