> Repository info for a stack can contain any number of repo definitions.  For HDP, there
are two repos used (HDP and HDP-UTILS).  When checking repositories for duplicate URL, the
code does this:
> {noformat}
> if (! repositoryEntity.getRepositoryId().startsWith("HDP-UTILS") &&  // HDP-UTILS
is shared between repo versions
> ! existingRepoVersion.getId().equals(repositoryVersion.getId())) { // Allow modifying
already defined repo version
> existingRepoUrls.add(repositoryEntity.getBaseUrl());
> }
> {noformat}
> We should make the unique declaration directly for the repository so authors don't have
to guess.  This entails:
> * Change {{repoinfo.xml}} to support a {{<unique>}} element within {{<repo>}}
> * {{<unique>}} should apply to, say, versions of HDP that change with each release.
 Absence of said element implies {{false}} for backward compatibility.
> * Change {{RepositoryVersionResourceProvider.validateRepositoryVersion(...)}} to use
this boolean for uniqueness check.
> * Update the {{version_definition.xsd}} to include this new element.
