Task #8385: Deprecate `BaseDistribution` and associated objects, in favor of new `Distribution` model with 3.12 - Pulp

Task #8385

Updated by bmbouter about 3 years ago

Deprecate the `BaseDistribution` model, `BaseDistributionSerializer`, `BaseDistributionViewset`, `PublicationDistribution`, and `RepositoryVersionDistribution` `BaseDistributionViewset` objects in the plugin API. Instead plugin writers should use API in favor of the new `Distribution`, `DistributionSerializer`, and `DistributionViewset` objects.
