Bug 1179356

I'm creating sync plans and repositories assignments among other things automatically via hammer tool.

e.g.:

$ hammer sync-plan create --interval=daily --name='Daily sync' --organization=$ORG

When I want to assign the sync plan to a product I need to list all sync plans, get an id and then assign the sync plan to product via the id because referencing of sync plan by name fails:

$ hammer product set-sync-plan --sync-plan='Daily sync' --organization=$ORG --name='Red Hat Enterprise Linux Server'
Could not assign synchronization plan.:
  Error: option '--sync_plan_id' is required

The solution is to add --label option that will assign a tag to a sync plan or repository so that there is no ambiguity in sync plan/repo specification.

Needing to manually parse IDs is just a design flaw as there is no reason to even have --sync-plan, etc. options when they are ambiguous.
