Upgrade barman-cloud library to v0.5.1 which includes lz4 support for
base backups. Update CRD schema and manifest to expose lz4 as a valid
compression option, and clarify docs that lz4 is no longer WAL-only.

Closes #867

Numbers come from a 2021 Barman proof of concept ([EnterpriseDB/barman#344](https://github.com/EnterpriseDB/barman/issues/344#issuecomment-992547396)), which predates `lz4` support for base backups. `lz4` is not yet benchmarked.
