Load several DB Connections at once

[meads]

Right now as far as I know you need to add each DB connection manually. This works... but is quite time consuming when trying to run tasks against a cluster of prod databases. It would be awesome to pass a JSON config file,example below, to the Alteryx Engine and have Alteryx create those connections upon parsing the file. This would save tons of time, and allow teams to share a central config file with consistent aliases across their clusters to ensure their app connections point to the same DBs across workflows. It would also make on boarding a breeze for new developers on team.
