Refactor & fix some issue for Monitoring

checking

**Issue:**
https://github.com/rancher/rancher/issues/18104

**Issues:**
https://github.com/rancher/rancher/issues/18166

**Problem:**
- Remote reader mode only allow `project-level` Prometheus to share the
metrics from `cluster-level` Prometheus
- Remote reader mode cannot save the namespace-related metrics from
`cluster-level` Prometheus

**Solution:**
- Add `prometheus.sync.mode` to choose
- Add a "federate" scrape job when deploying federation mode

**Issue:**
https://github.com/rancher/rancher/issues/17390

**Problem:**
Cannot input like `x.y.z/k` label name into serviceSelectorLabels

**Solution:**
Use array instead of object as values

**Problem:**
Cannot input like `x.y.z/k` label name into nodeSelector

**Solution:**
Use array instead of object as values

**Issue:**
https://github.com/rancher/rancher/issues/17340

problem:
We can not deploy monitoring tools in an
air gap environment.

Solution:
Add the ability to use the private image registry when deploying
monitoring tools

Issue:
https://github.com/rancher/rancher/issues/17842

**Problem:**
- Previous charts cannot satisfy the project level monitoring deploying design
- Grafana cannot be restarted after password changed
- node-exporter cannot be scheduled to `controlpane` or `etcd` role nodes
- Prometheus cannot be started with PVC that provided by some storage provisioner which don't respect the `SecurityContext`

**Solution:**
- Deploy "project level" monitoring with a permission-limit Prometheus
- Remove Grafana account `Secret` and use provisioning instead of `grafana-watch`
- Modify node-exporter `taints`
- Add configurable `SecurityContext` for Prometheus and Alertmanager
- Narrow Prometheus permission

problem:
After we refactored the logging, we can not deploy logging tools in an
air gap environment.

Solution:
Add the ability to use the private image registry when deploying logging
tools

Issue:
https://github.com/rancher/rancher/issues/17568

Problem:
we want to use catalog to deploy system tools

Solution:
add logging chart

**Problem:**
Can't enable project level monitoring without resources quota

**Solution:**
Add resource quota to workload spec

**Issue:**
https://github.com/rancher/rancher/issues/16993

**Problem:**
Grafana still can't mount PV correctly in Cloud, because there are 2
`securityContext` and `fsGroup` only work on Pod spec.

**Solution:**
Change the `securityContext` to Pod spec.

**Issue:**
https://github.com/rancher/rancher/issues/16953

This reverts commit cb0f92308e32c637a5cd09b5c1b7a644378bb58a.

Problem:
There isn't `fsGroup` in Container `securityContext`

Problem:
- Grafana can't mount PV correctly in Cloud

Solution:
- Use SecurityContext
