Description of the problem:

When a Cluster Logging instance is created with only Vector, the collector pods fail to start with below error as no vector.toml configuration is generated.

oc logs collector-9hmbk -c collector
Dec 13 07:30:43.534  INFO vector::app: Log level is enabled. level="debug"
Dec 13 07:30:43.534  INFO vector::sources::host_metrics: PROCFS_ROOT is unset. Using default '/proc' for procfs root.
Dec 13 07:30:43.535  INFO vector::sources::host_metrics: SYSFS_ROOT is unset. Using default '/sys' for sysfs root.
Dec 13 07:30:43.535  INFO vector::app: Loading configs. path=[("/etc/vector/vector.toml", Some(Toml))]
Dec 13 07:30:43.540 ERROR vector::cli: Configuration error. error=No sources defined in the config.
Dec 13 07:30:43.540 ERROR vector::cli: Configuration error. error=No sinks defined in the config.

Steps to reproduce the issue.

1 Deploy Cluster Logging and Elasticsearch operator version 5.4.

2 Create a Cluster Logging instance with only the Vector collector.

apiVersion: "logging.openshift.io/v1"
kind: "ClusterLogging"
metadata:
  name: "instance"
  namespace: openshift-logging
spec:
  managementState: "Managed"
  collection:
    logs:
      type: "vector"
      vector: {}

3 Check the collector pods. The pods are failing to start with error:

oc logs collector-9hmbk -c collector
Dec 13 07:30:43.534  INFO vector::app: Log level is enabled. level="debug"
Dec 13 07:30:43.534  INFO vector::sources::host_metrics: PROCFS_ROOT is unset. Using default '/proc' for procfs root.
Dec 13 07:30:43.535  INFO vector::sources::host_metrics: SYSFS_ROOT is unset. Using default '/sys' for sysfs root.
Dec 13 07:30:43.535  INFO vector::app: Loading configs. path=[("/etc/vector/vector.toml", Some(Toml))]
Dec 13 07:30:43.540 ERROR vector::cli: Configuration error. error=No sources defined in the config.
Dec 13 07:30:43.540 ERROR vector::cli: Configuration error. error=No sinks defined in the config.

4 Check the generated vector.toml. The config file is empty.
