description:
- "If set, this module will wait for the PVC to become bound and CDI (if enabled) to finish its operation
before returning."
- Module is aware of WaitForFirstConsumer and will not erroneously time out in such cases.
- "Used only if I(state) set to C(present)."
- "Unless used in conjuction with I(cdi_source), this might result in a timeout, as clusters may be configured
to not bind PVCs until first usage."
