Create a Social Share Component.
This component is not to be included with the MTK but should rather be an independent light module available via npm.

AddToAny is chosen as the social share provider because it is simple, loads fast, and does not require a customer account.

(Also it integrates automatically with Google Analytics - as many of them do.)

Implement as described in link Demo Project ticket: https://jira.magnolia-cms.com/browse/MGNLDEMO-105
