SyncPlans via CLI no longer needs organization-id.

Thanks to https://github.com/Katello/katello/pull/3918 we no longer need
to pass the organization-id to update, delete or get information for an
exising SyncPlan. All SyncPlan methods have been updated accordingly as
well as all tests.
Removed all data values containing Latin1 chars.
Merge pull request #660 from omaciel/syncplan-sans-org-id
