5bf11813e6 lownodeutilization: evictionLimits to limit the evictions per plugin 
In some cases it might be usefull to limit how many evictions per a
domain can be performed. To avoid burning the whole per descheduling
cycle budget. Limiting the number of evictions per node is a
prerequisite for evicting pods whose usage can't be easily subtracted
from overall node resource usage to predict the final usage. E.g. when a
pod is evicted due to high PSI pressure which takes into account many
factors which can be fully captured by the current predictive resource
model.

57a04aae9f chore: add descheduler plugin example 
This commit adds a sample plugin implementation as follow:

This directory provides an example plugin for the Kubernetes Descheduler,
demonstrating how to evict pods based on custom criteria. The plugin targets
pods based on:

* **Name Regex:** Pods matching a specified regular expression.
* **Age:** Pods older than a defined duration.
* **Namespace:** Pods within or outside a given list of namespaces (inclusion
  or exclusion).

To incorporate this plugin into your Descheduler build, you must register it
within the Descheduler's plugin registry. Follow these steps:

1.  **Register the Plugin:**
    * Modify the `pkg/descheduler/setupplugins.go` file.
    * Add the following registration line to the end of the
      `RegisterDefaultPlugins()` function:

    ```go
    pluginregistry.Register(
      example.PluginName,
      example.New,
      &example.Example{},
      &example.ExampleArgs{},
      example.ValidateExampleArgs,
      example.SetDefaults_Example,
      registry,
    )
    ```

2.  **Generate Code:**
    * If you modify the plugin's code, execute `make gen` before rebuilding the
      Descheduler. This ensures generated code is up-to-date.

3.  **Rebuild the Descheduler:**
    * Build the descheduler with your changes.

Configure the plugin's behavior using the Descheduler's policy configuration.
Here's an example:

```yaml
apiVersion: descheduler/v1alpha2
kind: DeschedulerPolicy
profiles:
- name: LifecycleAndUtilization
  plugins:
    deschedule:
      enabled:
        - Example
  pluginConfig:
  - name: Example
    args:
      regex: ^descheduler-test.*$
      maxAge: 3m
      namespaces:
        include:
        - default
```

- `regex: ^descheduler-test.*$`: Evicts pods whose names match the regular
  expression `^descheduler-test.*$`.
- `maxAge: 3m`: Evicts pods older than 3 minutes.
- `namespaces.include: - default`: Evicts pods within the default namespace.

This configuration will cause the plugin to evict pods that meet all three
criteria: matching the `regex`, exceeding the `maxAge`, and residing in the
specified namespace.
