These consts and types were moved to a separate metadata package in commits
292713c887 and 4321293972,
and deprecated in 72f76f2720, 5876b2941c,
and 6fa7d18320.
This removes the deprecated aliases in `cli-plugins/manager` in favor of
their equivalent in `cli-plugins/manager/metadata`:
- `CommandAnnotationPlugin`
- `CommandAnnotationPluginVendor`
- `CommandAnnotationPluginVersion`
- `CommandAnnotationPluginInvalid`
- `CommandAnnotationPluginCommandPath`
- `NamePrefix`
- `MetadataSubcommandName`
- `HookSubcommandName`
- `Metadata`
- `ReexecEnvvar`
