Provision graph doesn't apply netboot options to nodes

[Stanislaw Bogatkin]

When provision graph is applied, netboot options are managed only for one cluster node. We should fix it.

Steps to reproduce:
1. Install master node
2. Create cluster, start it with graph sequences.

It will fail on deployment stage cause some nodes won't switch to provision images.
