> MR-279: Install sanitized poms for downstream sanity

> Key: MAPREDUCE-2432

> Fix For: 0.23.0

> Due to [MNG-4223|http://jira.codehaus.org/browse/MNG-4223], the installed
> POMs of MR-279 is downstream hostile. E.g., it's impossible to use versions
> of hadoop-mapreduce-client-core.version in ivy other than 1.0-SNAPSHOT
> without changing the multiple POMs, rendering the version properties
> (hadoop-mapreduce.version and yarn.version) practically useless.
> This patch will install POMs with version (only) properties expanded. This
> patch also use inheritance and dependencyManagement to make POMs DRYer. It
> could use further cleanup to reduce "unnecessary" dependencies in some
> modules, but it's a working start.
> To see the patch work, apply the patch and do a mvn clean install -P-cbuild
> -DskipTests to make sure sane POMs are installed and then working on
> individual test issues.
