History
popcor255 2f1f8b32fc Updated helm catalog to access external helm repos 
As a user, I would like to use helm repos to deploy my applications. A helm chart was added to support this usecase. As a user having a chart called helm-update and helm-update repo is confusing. Helm charts were renamed and the tests were updated. As a user having all caps params can be confusing because they are reserved for environment variables. Charts were updated for increased readadbility.
