Make ImportExportManager available to plugins

I've been trying to create a cross-product way of doing restores through a REST resource. This would make life much simpler for doing integration tests in that we could put applications into a "known" state before a test is run. I tried writing a REST resource to do this for Bamboo, but found that I could not get the ImportExportManager injected.

Any chance of we can make this available to plugins for uses such as this?
