The provisioning config can be optionally stored in the ProvisioningConfig
configMap which is then passed to initcontainer through the volume mount.
There's also a possibility for a node specific congfiguration through
passing a nodename via NODE_NAME into initcontainer's environment
and passing a node specific profile via configMap volume mount.
