Remove sorting from Template#getObjects

[manusa]

Template sorts objects in when retrieved through the getter using HasMetadataComparator.

@rohanKanojia @manusa this may be a silly question, but why is sorting required?

No idea, I guess that at some point the order on which the items was applied was important.
Traced it back to fabric8io/kubernetes-model@78ab3a6#diff-4a305396a3d2548c17df3329d5251eda2dca65c060f858588d99068cc7d205e9

If a reference can't be found, I'd say this behavior seems undesirable. Based upon HasMetadataComparator (which seems somewhat arbitrary) it look like a pretty print option that was added to KubernetesList and Template. Ideally it should optional or the user's responsibility.
