Retries are done by default because keyservers can be unreliable.
Additionally, there is no way to determine the difference between
a non-existant key and a failure. In both cases gpg (at least 2.2.4)
exits with status 2 and stderr: "keyserver receive failed: No data"
It is assumed that a key provided to cloud-init exists on the keyserver
so re-trying makes better sense than failing.
@param key: a string key fingerprint (as passed to gpg --recv-keys).
@param keyserver: the keyserver to request keys from.
@param retries: an iterable of sleep lengths for retries.
