Automatically try reloading failed images on network changes (#3170)

* Add the networkMonitor to the NSE and delete the old MockMediaLoader

* Generate a MediaLoaderMock through AutoMockable and use it in the MediaProviderTests

* Implement an ImageProvider mechanism that automatically tries reloading images when connectivity is established again and use it for LoadableImages

* Merge the ImageProvider protocol back into the MediaProvider

* Address PR review comments

* Provide a default sdk client request configuration

* Address tasks not automatically cancelling themselves when views get deallocated
