Remove intelrtd.Manager interface, since we only have a single implementation, and do not expect another one. Rename intelRdtManager to Manager, and modify its users accordingly. Remove NewIntelRdtManager from factory. Remove IntelRdtfs. Instead, make intelrdt.NewManager return nil if the feature is not available. Remove TestFactoryNewIntelRdt as it is now identical to TestFactoryNew. Add internal function newManager to be used for tests (to make sure some testing is done even when the feature is not available in kernel/hardware). Signed-off-by: Kir Kolyshkin <kolyshkin@gmail.com>
