Epic Name: Management Packs: Repository Version Refactor

> We need to remove/refactor the {{repo_version}} table. This means the
> relationships tied to {{repo_version}} will also need to be replaced. Some of
> the high-level work items are:
> - Associate MPack's with Repositories
> - Remove {{host_version}} and add new relationships for mpack installations
> on hosts
> - Change Upgrades to track Mpacks not repos
> !ERD.png!
> \\
> - Removed repo_version table as it no longer serves a purpose (multiple
> mpacks of different versions can now come from the same repo)
> - Replaced the {{host_version}} table with {{mpack_host_state}} to represent
> whether an mpack was correct installed on appropriate hosts
> - Changed upgrade history to track the differences between 2 mpacks for a
> service group. This links back to an upgrade as well so we can have 2 SG's
> with 2 mpack source/targets in a single upgrade (think HDPCore and EDW in 1
> upgrade plan)
> The entity associations would look like:
> {code}
> /*
> Each Mpack has a collection of OS's, each OS with different URLs
> Redhat6, Redhat7, Ubuntu12
> */
> MPackEntity.getRepos() -> List<RepoOSEntity>
> /*
> The OS can have any number of URLs
> HDP: http://repo.ambari.apache.org/hdp
> HDP-UTILS: http://repo.ambari.apache.org/hdp-utils
> HDP-GPL: http://repo.ambari.apache.org/hdp-gpl
> */
> RepoOsEntity.getRepoDefinitions() -> List<RepoDefinitionEntity>
> /*
> HDP-Core-Default
> Mpack 3.0.0.0 -> 3.0.0.1
> MPack 3.0.0.1 -> 3.1.0.0
> */
> ServiceGroupEntity.getUpgradeHistory() -> List<UpgradeHistory>
> UpgradeHistoryEntity.getSourceMPack() -> MPackEntity
> UpgradeHistoryEntity.getTargetMPack() -> MPackEntity
> /*
> Mpack HDP Core 3.0.0.0 -> Hosts 1, 2, and 3 are OK
> Mpack HDP Core 3.1.0.0 -> Hosts 1 and 2 are OK, Host 3 is INSTALL_FAILED
> */
> MPackEntity.getHostInstallState() -> List<MPackInstallState>
