This was mainly for RU and Stop-the-World, in which it doesn't make sense to register a repo
for a version if no upgrade pack supports its.
However, you can also argue this case. Assume that the customer is on HDP 2.2, and HDP 2.4
is already out, and we only support upgrade packs for HDP 2.2->2.3, and 2.3->2.4. In
this case, the user should perhaps be allowed to register both repos, and then perform 2 RUs,
first from 2.2->2.3, and then 2.3->2.4
