Agents and Nodes (referred to in this segment as `clients`) communicate
with the Warble Server using a three-stage protocol:
-1. First time a client is started, it generates an async key pair for
- encryption and subsequent verification/signing. The private key is
- stored on-disk on the client host, and the public key is sent to the
- node registry on the master, along with a request to add the client to
- the node registry as a verified client. The Server registers a unique
- API key for each client, and binds the public key to this API key.

2. Once verified, a client can request test targets and parameters from
the node registry at the Server. This data is sent back to the client
