I can see that you had to copy a lot of code from `PackagedProgram` because
`flink-runtime` does not have a dependency on `flink-clients`. Also,
`JobWithJars` had to be moved to the `flink-runtime` module. I think we should
try to avoid duplicating the code in `PackagedProgram`. After talking to
@tillrohrmann offline, we think that we could achieve this by putting the new
`JarUploadHandler` into the `flink-runtime-web` module. This module already has
a dependency to `flink-clients` and `flink-runtime`. In `WebMonitorEndpoint`,
the jar handlers could be dynamically loaded according to whether
`flink-runtime-web` is in the classpath or not; similar to the
`StaticFileServerHandler` (see `WebMonitorUtils.tryLoadWebContent()`). What do
you think?
