Following changes are made:

• Changed the package from podgangset to core as now we have more than one CR types.
• Added code to detect all strongly connected components a.k.a cycles via tarjan's algorithm. Now we will be able to show all cycles in the error message. Also wrote unit test for implementation of algo to find strongly connected components a.k.a cycles.
• Refactored validating webhook.
• Regenerated deepcopy functions and client post API changes.
• Removed config/crd/bases which used to have generated CRDs. These are instead part of the API itself.
• Introduced a new API to expose CRDs programmatically. This allows people to provision operator programmatically as well.
