collect-logs only does not capture /var/lib/cloud/seed input files while creating a log tarfile. These files can be helpful in understanding what the image or datasource is using as input to cloud-init.

Also be more failure tolerant of /var/lib/cloud/instance not yet being present in undiscovered datasources environments. (DatasourceNone)

Also per https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1775086 /var/lib/cloud/instance may not yet exist in error'd environments.
