Add Kitchen CI & Yum repos

[epcim]

Added some basic kitchen CI configuration and yum repos + fixes to pass converge on centos 7.1.

I think it's better to either mark commented out blocks like this with a TODO or simply remove them altogether. Similar like this:

# TODO: zabbix_ng::sender

Hi, thanks for your contribution!
I basically think this is good work and a good idea, I added some minor thoughts in the code comments.
Please review and add your thoughts!

What does the kitchen CI actually test? We didn't implement any tests, did we?
If it doesn't actually check anything besides that the recipe runs through, we should split the kitchen CI into a seperate pull request and merge it later when there's actual integration/ unit tests available.

Thanks for the comments. Well mostly the things I forgot in code while already working on another branch/feature. I suppose they are now mostly fixed, except TODO, vs TODO: (anyway some removed in future PR).

Kitchen verifier just now does nothing, except test for successful converge. In my wrapper I have now an recipe for simple mysql/(pgsql) database. I will consider to share these, but better into kitchen "test" cookbook & integration testing, than as a recipe in zabbix_ng (as everybody has different preferences regarding DB configuration).

Wait a day or so before mege - as I still running "kitchen test". Anyway I will provide soon another PR for "rhel" platform family and a PR with zabbix version specified in attributes. These stacks in this order.

[epcim]

well the tests passed on my side, the current conflict is due updates in your master now ( regarding zabbix_version attr ).

BTW: can you pls share your idea about versioning, aka PR #3 is OK or the way it's done violate your personal flavors ;-) ?

[chr4]

Sorry, I'm a little confused by the many pull-requests. #3 seems to be the latest one? Or did you split them up? Can you close the ones that are not up to date please?
I'll comment on #3, as I think this is the current one. If I'm wrong, please advise :)

[epcim]

#3 is the latest, it's based on #2 and that on #1 (it would be too complex to split them as they interact). Sorry for confusion. My original aim was not to do much, but I ended up with three major updates as I was implementing it localy.
