Multiple configs

[mrmoss]

Description

1. Command sumocli login seems to have been replaced with sumocli configure but docs were not updated
2. Addresses Add the ability to have multiple credential profiles  #91 by adding an environment variable to select which configuration name is loaded via viper

Note: Someone from sumo should probably build the sumocli binary and upload it here...because I wouldn't trust me.

Before

Command sumocli login is in the docs but sumocli configure is used

Configuration was hardcoded to creds

After

Command sumocli configure is in the docs and sumocli configure is used

Configuration is determined by env["SUMO_CONFIG_NAME"] || "creds"
