• Feature Request

What should the feature do:
The prometheus module is always enabled. want to disable the prometheus module,

What is use case behind this feature:
The setting for monitoring.enabled: false and disable the module, true wiil enable

Enable prometheus module code by default is here:

rook/pkg/operator/ceph/cluster/mgr/mgr.go

Line 321 in 6273bc1

startModuleConfiguration("prometheus", c.enablePrometheusModule)

Environment:

My expression is pool. The issue want to config mgr module prometheus enable or disable. Maybe It is not associated with monitoring.enabled

When cluster is init, you can prometheus will be init too:

ceph mgr services
{
    "dashboard": "http://10.9.8.102:8080/",
    "prometheus": "http://10.9.8.102:9283/"
}

We can't disable prometheus via crds

It seems prometheus module could set disable here. Unfortunately, it has no effect after setting in my test.

I wish mgr prometheus module's port and enabled staus could be set by crds, just like DashboardSpec.
