I think we already have a katello feature here #69
I'll rebase the PR and update accordingly.

@kgaikwad You may have a look and see if it meets the purpose?

@swapab ,

I have already added katello-service feature in qpidd PR.
Could you please check PR #52.

We have some queries related to PR #52 that's why I marked it as On-Hold.
To unblock other PRs, I have separated out the code into this new PR.

@swapab ,

One more thing I forgot to mention here is that katello & katello-service are two different things.
katello is plugin and katello-service comes under katello-packaging using which we can perform actions like start/stop/status for few services. So we can't mix these two.

@kgaikwad Got it.

I think it would be sensible to add katello-service under definitions/services/

Based on scrum call discussion, I'm ok with leaving this one as is and not introducing another namespace for now. Thanks @kgaikwad
