initial commit for MeasurementOOBManagerBeanTest
adding support for making overlord available via CDI injection

Lots of tests have boiler plate code to obtain the overlord. With this commit,
you can now do,

public class MyTest {
    @Inject @Overlord
    private Subject overlord;
}

That will inject a cached copy of the overlord eliminating extra calls to the
database.

Bug 885664 OpenSSHD and MySQL availability check may report stale data

Refactoring of ProcessInfo
The class has now a subtype which groups non static data and operations on this data.
The purpose is to make clear for users of the class that it caches data and only takes snaphots via SIGAR calls

OpenSSHDComponent and MySQLComponent have their availability check fixed and using this API

Other classes were updated with new API calls for isRunning method

Add lock and interval mechanism to ProcessInfo refresh
This will avoid SIGAR bug when making too close calls to getProcState
Add corresponding test

make sure we clean up when downloading jboss distro

The ant script that downloads the jboss distro could time out leaving a corrupt
zip file in the tmp dir. This would cause the build to fail and was also
causing subsequent CI builds to fail. Once again, doing tear down in the set up
fixes the problem.
