Is this a plausible scenario if this is called from the CLI? If the default is 0, can we add a debug log here?
Can a user set a negative number? It might be worth it making it a uint?

Added threshold validation for
RunDKGandRunReshareDKG. Previous behavior delegated the check down the stack to allow underlying library (kyber) to validate the threshold. Given that Kyber has weak validation that can lead to weird late errors, it is more convenient to verify the threshold upfront.Additionally added verification such that users cannot remove all nodes with "remove operators" command.
