SPARK-5143 [BUILD] [WIP] spark-network-yarn 2.11 depends on spark-net…

…work-shuffle 2.10

Update `<scala.binary.version>` prop in POM when switching between Scala 2.10/2.11

ScrapCodes for review. This `sed` command is supposed to just replace the first occurrence, but it replaces them all. Are you more of a `sed` wizard than I? It may be a GNU/BSD thing that is throwing me off. Really, just the first instance should be replaced, hence the `[WIP]`.

NB on OS X the original `sed` command here will create files like `pom.xml-e` through the source tree though it otherwise works. It's like `-e` is also the arg to `-i`. I couldn't get rid of that even with `-i""`. No biggie.
