Add an API for page view retrival to show on the page it self

[rehanvdm]

Thinking of caching the page url + page views number in a DDB table, TTL of say 15 minutes. BUT this will scan over all the partitions. So instead, let's instead scan over the last 30 days and then this feature has a liveliness counter to it as well. The average read time can also be exposed like this.
