Ability to unregister validator nodes

[ebruoguzberk]

Description: Nodes that do not have a stake and support the SKALE chain should be able to unregister.

Leading Solution: If a delegator undelegates, nodes supporting SKALE chains should have the ability to exit, and chains should be assigned to new validator nodes. Use node rotation to assign the SKALE chain to the new validator node.

Alternative solution:
Often, delegators want to change a different commission fee or a different validator. Just like we give the option to change the validator's public address to something else... Nodes can be reassigned to another validator.
