Use wildcard-style patterns when specifying the blocklist nodes list

[nikola1003]

The current way we specify the list of nodes to be added to the blocklist could be more convenient and faster, as all the nodes need to be explicitly listed. Can we use a similar style of list as for cctl?

Most of the time, one would have to power off nodes via cctl and also issue blocklist command. It would be great if the two would require the same input.

FYI: the cctl pattern expansion code is here:
