Add extra and context attributes to Internal events tracking on frontend

Problem

While calling snowplow from Internal events, We are just passing eventname (action). If there are some extra information apart from Category, Label and value should be sent. (We are ignoring those values according to !118928 (merged))

Currently, there is no way to send extra attribute to snowplow standard context.

Reference - !130484 (comment 1536535559)

Desired Outcome

Internal event should send all the extra and context attributes to snowplow.
