Retry 6 times every 60 seconds to get a node from cico for weirdo jobs

There are temporary heavier rate limiting on cico due to a misbehaving
tenant, let's put some retries in place to alleviate the issues with
getting nodes.
Since the rate limiting is based on "amount of nodes per 5 minutes",
let's retry for at least 6 minutes before giving up.
