7.x nodes permit the on-disk cluster metadata to omit the manifest file in order to support upgrades from 6.x. We are similarly lenient in `master`, i.e. 8.x, but there is no need to be since we must be upgrading from a 7.x node which ensures that the manifest file is written. We prefer to keep this lenience (see elastic#52412) so this commit removes the commented-out indications that it should be removed. The new metadata format introduced in elastic#50907 means that this whole subsystem will be removed in v9 anyway. Relates elastic#38556
