It resolves #221

Whats the status of this PR? Would be very happy to see this land? cc/ @yoichitgy

This would have been handy to have at the moment for me as well; I could create an extension function if only container wasn't private.

Edit: I spoke too soon. This extension appears to be working for me:

extension Assembler {
    public var synchronizedResolver: Resolver {
        let internalResolver = resolver
        if let it = internalResolver as? Container {
            return it.synchronize()
        } else {
            return internalResolver
        }
    }
}

Any updates? cc @mpdifran

Hey @peterkos, with #514 and #523 this should be resolved on 2.8.3. (as long as you use a synchronized Container)
