[FAB-2662] Implement CouchDB docker config
https://jira.hyperledger.org/browse/FAB-2662 Changing the CouchDB dockers used in fabric to use recommended configuration (couchdb local.ini). Include config comments in local.ini stating how to enable user security. Also, making sure that all CouchDB unit-tests follow the same procedure for setting up address and login credentials. Including test comments stating how to run tests against CouchDB with user security enabled. Change-Id: I975d04d757d0371c8db03acf0ddcf92c01c35f8c Signed-off-by: Adnan Choudhury <[email protected]> Signed-off-by: denyeart <[email protected]>
