BUG: as an admin user, every page load in the dashboard results in a "get mapping" call

[dustinrue]

Describe the bug

If you are a full admin user, then every page load within the admin dashboard results in a remote call to Elasticsearch to fetch the mapping. This adds a significant amount of time to each page load.

Steps to Reproduce

1. Be a user with the Administrator role
2. Enable the plugin
3. Browse the admin
4. Suffer with longer page loads

Expected behavior

The mapping currently installed vs what is expected probably won't change often or ever until a plugin update is performed.

My suggestion is to rewrite notices routines so they happen on wp-cron rather than inline with page requests. Use transients to store the results of the checks and display noticed based on what the transient says. Cache this information and don't refresh it unless necessary.
