3.19 - Preconnect to external domains - Exclusion filter

[piotrbak]

User Story

As a user, I want to exclude some URLs from automatic preconnect

Acceptance Criteria

• Exclusion by domain or attribute (it can be done by a full match, if it’s easier for engineering)
  • Exclusion is possible using a filter (guarded) or from backend
    • Filter is guarded
    • static.cloudflareinsights.com to be added to the backend
    • Arguments excluded by default rel=profile or rel=preconnect or rel=dns-prefetch or rel=icon to be added to the backend

We will need to check with SaaS team how those those attributes' exclusions will be added like rel="profile" and others, so in our code we can exclude them correctly.
