Ask for feedback on the Agent listing page

Proposal

Ask for feedback about the GitLab Kubernetes Agent on the Agent listing page when there is already at least 1 agent.

The feedback issue is at #342696

Example from another team

Copy:

Tell us your experience with the GitLab Agent in this feedback issue.

• Make it dismissible
• Provide a feature flag so self-managed users can switch it off at their instances

added GitLab Core groupconfigure [DEPRECATED] typefeature labels

added to epic &4739

Setting label(s) ~"devops::configure" sectionops based on ~"group::configure".

added devopsconfigure [DEPRECATED] sectionops labels

changed milestone to %Backlog

added candidate14.8 label

@anna_vovchenko Would it make sense to schedule this together with #340882 (closed) only because both change the Agent listing UI or you'd prefer to tackle them totally independently?

@nagyv-gitlab I'd prefer to work on them independently as they change different components.

Should we place the feedback alert both on the All and Agent tabs? I think yes, as it's more likely for users to see it on the All tab.

Should the alert be dismissable? I think yes, but want to double-check

@anna_vovchenko Yes (on both tabs) and No (it should not be dismissible). Thanks for asking! We will remove it in a few months. On the other hand, it might be nice to have a feature flag (on by default) so self-managed users can switch it off.
