Description of problem:

Cannot deploy RPM packages you upload yourself via embedded Yum.

You see this:

2012-01-14 00:11:39,590 ERROR [ResourceContainer.invoker.nonDaemon-3] (org.rhq.plugins.platform.LinuxPlatformComponent)- Install packages failed
java.lang.NullPointerException
        at org.rhq.plugins.platform.content.yum.YumProxy.execute(YumProxy.java:160)
        at org.rhq.plugins.platform.content.yum.YumProxy.install(YumProxy.java:95)
        at org.rhq.plugins.platform.LinuxPlatformComponent.deployPackages(LinuxPlatformComponent.java:181)

modules/plugins/platform/src/main/java/org/rhq/plugins/platform/content/yum/Primary.java

It appears that PackageVersionMetadataComposite.getMetadata() returns null, resulting in NPE:

    private String gunzip(byte[] input) {
^^^ 

In fact, when you upload your own RPM, metadata is null. And AFAIK, metadata is always null for discovered resources.

Version-Release number of selected component (if applicable):

RHQ 4.1. Code is same in 4.3
