This moves to define the datasources provisioned by grafana via a template defined in the values.yaml. This allows us to define multiple datasource types that can be mapped directly to the corresponding entries in endpoints, which enables us to generate the data source urls via endpoint lookups rather than hardcoding this. This is the first step to support multiple data sources in a singular grafana deployment Change-Id: Iac7f4b1e07aaf83ae4d2a0c923cd06817f0d8c0d
