> Looking at ClusterManagementGroupManager#onElectedAsLeader we can see that REST authentication configuration is applied to the distributed configuration on leader election. This happens because there is no any other way to put any values to the cluster configuration on init. This leads to the following situation:
> - cluster init in progress, some REST endpoints are blocked (cluster/configuration for example)
> - cluster initialized, REST is available without auth 
> *anybody can use the REST*
> - authentication configuration is applied to the distributed configuration and REST is secured
> To fix this issue we have to design the solution for "atomic configuration initialization" of something like this.
