ExternalImagePiece

[luiztauffer]

ExternalImagePiece would allow the user to pass any docker image to run (e.g. with code to be executed in Go, JS, C++, etc...). The ExternalImagePiece would then run to perform all the necessary basic Domino actions in the Pod and the external Image would run as a side container, that would read input and write output in predefined paths shared with the main container, or as ENV vars.
