      Description of problem:

      While forwarding logs to rsyslog using vector, logs are being shipped even with wrong proto (and correct url), ex: url: 'xyz://rsyslogserver.openshift-logging.svc:514' ,  also no related error message is shown on collector pods.

      Version-Release number of selected component (if applicable):

      Logging 5.7

      Steps to Reproduce:

      1. Deploy rsyslog receiver 
      2. Create CLF with wrong url:
      apiVersion: logging.openshift.io/v1      
      kind: ClusterLogForwarder      
      metadata:      
        name: instance      
        namespace: openshift-logging      
      spec:      
        outputs:      
          - name: rsyslog-created-by-user      
            type: syslog      
            syslog:      
              facility: local0      
              rfc: RFC3164      
              payloadKey: message      
              severity: informational      
            url: 'xyz://rsyslogserver.openshift-logging.svc:514'      
        pipelines:      
          - name: forward-to-external-syslog      
            inputRefs:      
              - infrastructure      
              - application      
              - audit      
            outputRefs:      
              - rsyslog-created-by-user

              3. Deploy CL with vector

      Actual results:

      No related error message in collector pods.

      Collector pod logs:

      The collector is not throwing error for a wrong protocol. 

      $ oc rsh collector-5tv2k
      Defaulted container "collector" out of: collector, logfilesmetricexporter
      sh-4.4# vector validate /etc/vector/vector.toml
      Loaded with warnings ["/etc/vector/vector.toml"]
      ------------------------------------------------
      ~ Transform "route_container_logs._unmatched" has no consumers
      √ Component configuration
      √ Health check "rsyslog_created_by_user"
      √ Health check "prometheus_output"
      --------------------------------------------------------------
                                                           Validated
      

      Expected results:

      User should see the below error in collector pods:
      ConfigError error="valid options are udp,tcp but got xyz"

      Additional info: Works fine with fluentd
