Fix property names to spring.couchbase instead of spring.data.couchbase. Fix VaultConfigCouchbaseTests to make it work with Couchbase instead of using Cassandra.
Add CouchbaseSecretIntegrationTests to verify interaction through VaultConfigTemplate. Remove property overrides for username/password so that Vault PropertySources are used. Use unique role name to avoid clashes with other tests.
Enable VaultConfigCouchbaseDatabaseTests for ConfigData API by importing vault://. Update reference documentation.
Resolves gh-408.
