Add Eclipse launch tasks for the 0.20-security branch

                 Key: HADOOP-7277
                 URL: https://issues.apache.org/jira/browse/HADOOP-7277
             Project: Hadoop Common
          Issue Type: Improvement
          Components: build
    Affects Versions:
            Reporter: Jeffrey Naisbitt
            Assignee: Jeffrey Naisbitt
            Priority: Minor
             Fix For:

This is to add the eclipse launchers from HADOOP-5911 to the 0.20 security branch.

Eclipse has a notion of "run configuration", which encapsulates what's needed to run or debug
an application. I use this quite a bit to start various Hadoop daemons in debug mode, with
breakpoints set, to inspect state and what not.

This is simply configuration, so no tests are provided. After running "ant eclipse" and refreshing
your project, you should see entries in the Run Configurations and Debug Configurations for
launching the various hadoop daemons from within eclipse. There's a template for testing a
specific test, and also templates to run all the tests, the job tracker, and a task tracker.
It's likely that some parameters need to be further tweaked to have the same behavior as "ant
test", but for most tests, this works.

This also requires a small change to build.xml for the eclipse classpath.
