plugins

This commit introduces a deprecation warning for the `maven` plugin.

Because there's no such thing as an `ivy` plugin, we also deprecate

the _use_ of the `uploadArchives` task, which corresponds to uploading

with `ivy`, but is defined in the `base` plugin that we cannot

deprecate.

WorkerDaemonClients are retained across builds, so any object associated with

it must not contain project state since this will be kept around until the worker

expires.

- Introduce a newDecoratedJavaForkOptions which creates a decorated JavaForkOptionsInternal

- Replace calls to the decorated version of the method with non-decorated versions where appropriate
