Disable transfers in loki-local-config.yaml (grafana#1579)

* Disable transfers in loki-local-config.yaml

grafana#1425 added the ability to disable transfers by setting the max amount of retries to zero or lower. The PR, however, didn't change the default setting in loki-local-config.yaml. This commit changes the setting in loki-local-config.yaml to disable transfers since they would never succeed with the default settings of an inmemory ring anyway.

* Set `max_transfer_retries` to 0 in helm charts
