Hook up subscription lookup based on settings.

Authored by daniel.

Description

Hook up subscription lookup based on settings.

This allows sitelinks based subscription tracking, explicit subscription tracking,
as well as a hybrid mode, to be configured.

DEPLOY: if useLegacyChangesSubscription=true is set on the repo,
now set subscriptionLookupMode='sitelinks'. useLegacyChangesSubscription
remains in use for clients, and could be kept for the repo, in case we end
up rolling back the code.
