Description of problem:

When upgrading a cluster there needs to be a way to reconcile SCCs that are in the new code against existing cluster SCCs.  This needs to be a cli command.

The command should

1.  Always reconcile the definitions (everything except users, groups, and priority)
2.  Have an option to overwrite users, groups, and priority
3.  Always reconcile nil priorities with new values if set
4.  Show what will be reconciled and not save changes until --confirm is issued
