Using DynamicLoopingCall involved a few hacks to make it work properly. This
new BackOffLoopingCall will start an exponential backoff (with a configurable
jitter) when there is a failure. The backoff will continue until the given
function returns True or timeout is about to be exceeded. The function will
run indefinitely until either an exception is raised or timeout is reached.
I plan to merge this into oslo loopingcall and switch the heartbeat to this.

Currently, if a single lookup call to the Ironic API fails, the entire
agent errors out and restarts. This allows the agent to retry for a set
amount of time before throwing an uncaught exception forcing a restart.
