[foot]

Reverts #1806

This breaks passing cli flags into the cluster-service e.g.

❯ go run cmd/clusters-service/main.go --dev-mode
{"level":"info","ts":1673961951.795032,"logger":"gitops","caller":"app/server.go:334","msg":"Setting klog verbosity","verbosity":"0"}
flag provided but not defined: -dev-mode
Usage of /var/folders/c_/ksp92k1j6m56l4l_p83t8jf00000gn/T/go-build3592919515/b001/exe/main:
  -add_dir_header
    	If true, adds the file directory to the header of the log messages
  -alsologtostderr
    	log to standard error as well as files (no effect when -logtostderr=true)
  -kubeconfig string

  -log_backtrace_at value

  -log_dir string

  -log_file_max_size uint
    	Defines the maximum size a log file can grow to (no effect when -logtostderr=true). Unit is megabytes. If the value is 0, the maximum file size is unlimited. (default 1800)
  -logtostderr
    	log to standard error instead of files (default true)
  -one_output
    	If true, only write logs to their native severity level (vs also writing to each lower severity level; no effect when -logtostderr=true)
  -skip_headers

  -skip_log_headers
    	If true, avoid headers when opening log files (no effect when -logtostderr=true)
