The recently introduces `data_source_mismatch_penalty` property in the MetadataPlugin
class was not copied in the backwards compatibility layer. This PR
introduces a fixes this such that `cached_properties` are copied to
legacy metadata plugins.
This also includes a test for the expected behavior.

- Modified `_get_plugin` function to use `reversed()` when iterating
through `namespace.__dict__.values()`
- This ensures that we load _the last_ plugin class found in the
namespace.
Fixes#6093
Adds a `omit_single_disc` boolean configuration option to the zero
plugin for writing to files. Adds the logic that, if disctotal is set and
there is only one disc in disctotal, that the disc is not set.
This keeps tags cleaner, only using disc on multi-disc albums. The
disctotal is not touched, particularly as this is not usually displayed
in most clients.
The field is removed only for writing the tags, but the disc number is
maintained in the database to avoid breaking anything that may depend on
a disc number or avoid possible loops or failed logic.
A column of disc 1 makes me feel there should be a disc 2, when most
albums are a single disc only.
Change the parameter name to omit_single_disc (vs previously zero_disc_if_single_disc)
Add return of 'fields_set' so that, if triggered by the command line `beets zero`, it will still effect the item.write.
Added tests.
