[PULP-2058] pulp cli rpm publication create misses option for compression-type

[simenon]

Summary

When creating a publication there is an option to set the compression type of the metadata. If you define it with the cli there is no option to set the compression type, and, the compression type is not set to default, contrary what the manual states:

compression_type: Sets the compression type to be used by the repository metadata (primary.xml, filelists.xml, etc.) If not specified, the default Gzip algorithm will be used.

'<resource_type>' defaults to rpm.
--version INTEGER a repository version number, leave blank for
latest
--repo-config TEXT A JSON dictionary describing config.repo
file (or @file containing a JSON dictionary)

Additonal context

[sachintu47]

Wanted to +1 this issue. We need this option for our z/OS clients, which don't support compressed repository metadata and need plain XML.
