[FAB-5453] Enable CouchDB passwords in Fabric Samples

CouchDB usernames and passwords can be enabled by adding
additional environment variables to docker compose files.

The environment variables are added without values.
This will create peer and couchdb containers without
CouchDB passwords enabled.

Initializing the variables will create a CouchDB container
with and admin username and password.  The peer will also be
created with the CouchDB username in the ledger config.
