Repository management

[hatifnatt]

1. Why Debian repository key stored locally in formula repository? While RedHat keys fetched directly via http.
2. What need in multiple repo states why it can't be single state? And all other tricks like including state file as Jinja template and then using extend to declare requisites.
3. Why result of applying repo state is actually installed packages? I think it must only configure repository and it's all. Installation must be preformed in conf state, or may be even better in separate install state.

My thoughts on this:

• Repository state can be simplified, local file with gpg-key can be removed, if you can fetch packages from official repository, you also can fetch gpg-key from it. If you are using your own or 3-rd party repository, you don't need this key at all.
• Multiple zabbix.*.repo states can be simplified to single zabbix.repo old ones can be saved for compatibility. Extend can be done in installation state.
• I think there is need to be single repo state, if you wan't use official repo - include it in top file, or run via state.sls. Another approach also can be used control usage of official repo via pillar, like in php-formula may be it's even better to control everything via pillar.
• repo must not install anything except repository itself, package installation must be moved in conf or even better in separate install state.
