roachtest: add mutator to panic and restart a node

Open Dev-Kyle opened this issue 7 months ago • 1 comments

This change adds a new mutator that will enable the ability to randomly panic a node. Currently the node is immediately restarted upon crashing, with the end goal of being able to panic a node and waiting some number of steps before restarting it.
