Generic Vue Alert Component

What does this MR do?

Closes #197113 (closed)

This MR adds a generic wrapper of GlAlert so that our backend HAML files have a way to access a more flexible Flash message.

Testing outside of Unit Testing

I am not quite sure how to properly show that this component works outside adding it into a file temporarily for demonstration. Here is the extra code I added to get the screenshot below:

Add to top of /ee/app/views/admin/geo/nodes/index.html.haml

- if true
  .js-vue-alert{ data: { variant: 'tip', 
    message: 'This GitLab instance is licensed at the Core tier. Geo is only available for users who have at least a Premium license.',
    primary_button_text: 'Manage your license',
    primary_button_link: admin_license_path,
    dismissible: true.to_s } }

Add a new file ee/app/assets/javascripts/pages/admin/geo/index.js

import initVueAlerts from '~/vue_alerts';

initVueAlerts();
