feature request: add ability to restart apps from applications list page in ArgoCD

[audip]

Summary

A button to "Restart Apps" on the applications list page with the ability to restart selected apps.

Motivation

There are use-cases of a central ArgoCD cluster deploying to Kubernetes clusters across multiple AZs/regions around the world that need to be restarted when a cache invalidation event or another maintenance event happens. Rolling restart is an action that engineers at @myfitnesspal perform when pods aren't able to pick new IP address of Elasticache instances, actively performing incident response. So, I'd like to propose adding a button that we are using internally, see screenshots of how it looks and operates (very similar to the "Refresh Apps" button)

Proposal

The code is about ~100 lines as it is mostly a UI change with functionality to perform a rolling restart already existing. The source code is available for viewing in this pull request: #21307
