Adversarial tests for ciphernodes

[ryardley]

We are only testing happy paths for ciphernodes

We should begin to brainstorm test descriptions for tests we want to run against:

• ciphernode actor system
• live network tests (chaos net)

We don't need the tests written just the descriptions of the tests

[0xjei]

can we mark this as done given your recent tests on upgrades and dropping nodes in the middle? @hmzakhalid
