The documentation states that the command is used for creating user accounts for batch/role access. However this is not always the case; it is possible to create an account for a real person with an email address and name. Update the documentation to say that if the account is created without an email address, it may only be used for batch/role access. Change-Id: I213708e32f98585632810023afd9eca3e6f3df8e
