add timeout catcher w/ retries

[iynere]

for branches where the gap between commits is very, very large (ie, 100s or 1000s of circleci jobs), the orb can take 15+ minutes to run & make 1000s of api calls in rapid succession, which, when run in a parallelized job, can lead to timeouts.

a timeout should trigger an automatic retry

also, i wonder if this orb's command could just run as a deploy: (instead of run:) step, so it only ever uses 1 container.... parallelizing it certainly doesn't do anything, functionally, except bog it down
