Upgrade to n14 and serverless 3

Purpose

Upgraded 508 to serverless version 3 and upgraded the runtime node 14.

Serverless framework was updated from version 2 to version 3 in the top level package.json.
Runtime was updated from version 12 to version 14
As many plugins in the sls plugin ecosystem made updates to accommodate v3, all sls plugins were updated to latest ( yarn upgrade pluginname --latest ). No issues were found.
Deployment and app functionality was verified to work as intended.
