dist tag based permissions

[g3hxqe-contrib]

Is your feature request related to a problem?
I would like to allow publishing for authenticated users to publish to "development" dist tag but would like to restrict "latest" tag to be permitted by ci build servers.

Describe the solution you'd like
I would like to expose dist tag information to plugins, this way a plugin could implement the authentication logic on weather or not grant permission to the user depending on what tag they are publishing to.

Describe alternatives you've considered
I have looked at adding it to the core package authentication configuration. It seems as though it may be confusing to configure. "@myorg/***/@development". It seems like it wouldn't be common so might be better as a plugin, but the data needs to be passed along to the auth plugin api.

Great idea, just to remark it is only valid for publish and unpublish. But this will be nice for auth plugins to be able create more complex scenarios.
