Describe the bug

Argocd-application controller faces a memory leak when server url in application controller ends with a trailing / as described in argoproj/argo-cd#5578

To Reproduce

1. Edit any existing application object and append a / in the end in server.
2. Check resource usage of argocd-application-controller pods on Grafana

Current behavior

If an application object server url ends with a trailing /, argocd-application-controller memory usage keeps growing higher and ultimately gets OOMKilled.

Expected behavior

While the fix for this memory leak issue is in argocd-1.8.6 but meanwhile we can prevent user from entering the trailing / in server url on the UI and trim off any trailing slash while saving it.
