Create additional scratch org definitions

[allisonletts]

We need to decide how NPSP and EDA orgs, as well as the other boxes, work.

@allisonletts This is fairly easy technically but we will need a nomenclature for CCI orgs on the testing workflow.

1. Create a CCI org definition in the orgs folder. It can be as simple as cloning the existing org definition JSON and rename the file with an alias for a new CCI org - for example, npsp.json and eda.json
2. When connecting a CCI org, simply declare the new cci org alias at the end of ‘CCI org connect ’ or on the —org option
