Description of problem:
Right now the service-catalog errors out when trying to reconcile serviceplans on the ansibleplaybookbundle organization due to the fact that there are multiple plans labeled 'default'. We are assigning the planID as the plan name which conflicts since all of our APBs has a 'default' plan. 

Version-Release number of selected component (if applicable):
3.7.0

How reproducible:
100%

Steps to Reproduce:
1. Bring up the latest service catalog images with APBs in ansibleplaybookbundle as of 10/7


Actual results:
The following error in the controller manager pod:

Expected results:
All APBs are available and listed

Additional info:
We simply need to be setting planID to something globally unique
