Adding devices to discovery groups

Discovery groups simplify the process of working with a large number of devices and their corresponding IP addresses/hostnames and discovery credentials. For example, if you have set of four user/password credentials used among twenty devices, using a discovery group allows you to enter each set of credentials and all of the IP addresses/hostnames, and the discovery group will match the correct credentials to each device.
