Unknown flag --metrics-port when enabling prometheus on the operator

[nextrevision]

Expected Behavior

Enabling scraping on the prometheus operator should create a PodMonitor.

prometheus:
  operator:
    enabled: true
    podMonitor:
      enabled: true

Actual Behavior

The pod fails to start with the following error:

Usage of /keda:
      --disable-compression                   Disable response compression for k8s restAPI in client-go.  (default true)
      --health-probe-bind-address string      The address the probe endpoint binds to. (default ":8081")
      --kube-api-burst int                    Set the burst for throttling requests sent to the apiserver (default 30)
      --kube-api-qps float32                  Set the QPS rate for throttling requests sent to the apiserver (default 20)
      --kubeconfig string                     Paths to a kubeconfig. Only required if out-of-cluster.
      --leader-elect                          Enable leader election for controller manager. Enabling this will ensure there is only one active controller manager.
      --metrics-bind-address string           The address the metric endpoint binds to. (default ":8080")
      --metrics-service-bind-address string   The address the gRPRC Metrics Service endpoint binds to. (default ":9666")
      --zap-devel                             Development Mode defaults(encoder=consoleEncoder,logLevel=Debug,stackTraceLevel=Warn). Production Mode defaults(encoder=jsonEncoder,logLevel=Info,stackTraceLevel=Error)
      --zap-encoder encoder                   Zap log encoding (one of 'json' or 'console') (default )
      --zap-log-level level                   Zap Level to configure the verbosity of logging. Can be one of 'debug', 'info', 'error', or any integer value > 0 which corresponds to custom debug levels of increasing verbosity (default )
      --zap-stacktrace-level level            Zap Level at and above which stacktraces are captured (one of 'info', 'error', 'panic').
      --zap-time-encoding time-encoding       Zap time encoding (one of 'epoch', 'millis', 'nano', 'iso8601', 'rfc3339' or 'rfc3339nano'). Defaults to 'epoch'. (default )
unknown flag: --metrics-port

Steps to Reproduce the Problem

1. Enable prometheus scraping on the operator via values.
2. Deploy latest chart.

Thanks for reporting, that's definitely a bug, it should be --metrics-bind-address :(
