repoCredentials should not be set by default if not using private repo

[Hugo do Prado]

repoCredentials should not be set by default if not using private repo, otherwise it fails:

INFO: Load Pod an Container informations

for credential, credentialData in repoCredentials.items():
klustair-runnerjob
AttributeError: 'str' object has no attribute 'items'

Issue solved by deleting the repoCredentials line from secret. I'm not using private repo right now.
repoCredentials must only have values if explicitly specified with helm --set command
