We are going to want to be able to initialize collectors with specific configurations (the `--from-config` option will allow building a new manifest out of an existing collector config). So this changes the manifest initialization, out of a template, and to using the actual `Config` struct. I had to setup manual omission of nil/empty values, as mapstructure's omitempty seems to only ignore structs, not maps or strings.
