Extra attributes appearing in credential binding details

[Dray56]

According to the cloudfoundry docs, there does not seem to be any well defined schema for the details of a service credential binding. Though credentials seem to be present in almost every managed service instance details and some user provided service instances if credentials had been passed during their creation, syslogDrainURL is specific to user provided service instances and the 3 attributes are not always present in every response.

type ServiceCredentialBindingDetails struct {
	Credentials    map[string]any `json:"credentials"`
	SyslogDrainURL string         `json:"syslog_drain_url"`
	VolumeMounts   []string       `json:"volume_mounts"`
}

Therefore better approach would be to add omit empty for them so that the attributes do not appear in the response when the api did not return them
