Input: Some code to illustrate the problem, preferably in a state that can be independently reproduced on our end

Actual output: What did you observe? What errors did you see? Can you attach the logs? (Java logs, MarkLogic logs)

public static DatabaseClient newClient​(java.lang.String host,
                                       int port,
                                       java.lang.String database,
                                       DatabaseClientFactory.SecurityContext securityContext,
                                       DatabaseClient.ConnectionType connectionType)
Creates a client to access the database by means of a REST server. 

<<The CallManager interface can only call an endpoint for the configured content database of the appserver. You cannot specify the database when constructing a client for working with a CallManager.>>

Expected output: What specifically did you expect to happen?

Text within angle brackets needs to be removed for most of overloads of newClient​() method in DatabaseClientFactory class.

Alternatives: What else have you tried, actual/expected?

None.

JavaDoc should now mention data service instead of CallManager
