Installing the external-snapshotter CRDs and controller runs several
kubectl commands against raw.githubusercontent.com manifest URLs with
no retry, and getManifestFromURL did not retry either, nor did it check
the HTTP status code, so an error page could be fed to kubectl as a
manifest. Transient fetch failures showed up in TestCephSmokeSuite as
NFS test failures during snapshot CRD installation.
Retry the URL-based kubectl invocations and the manifest download, fail
on non-200 responses, and bump the snapshot controller wait in the file
test from 75s to 450s to match the block test since the
snapshot-controller image pull can take longer in CI.
