Remove the counter way to assign a vm_id as it didn't work reliably
Jira ticket: ALEPH-272
That method was broken when persistent instances were loaded at start up. Since the "new" feature that allow persistent instance across aleph-vm reboot if one was started then aleph-vm was stopped and restarted the counter method could reassign the ip and break the existing vm's.
Secundary reason was that the feature wasn't working properly with the default settings, as
2**available_bitsreturned 1. So that code path was only used if the node owner tweaked some undocumented settings making it hard to identify and debug in prod nodes.Self proofreading checklist
