Hammer CLI

Cloned from https://bugzilla.redhat.com/show_bug.cgi?id=1255086

Description of problem:
Hammer reads a set of config files at start. If in the local directory there is a file called "config" it tries to read it as a hammer config file. However, the hammer documentation stated it should only read config files from a local directory named config, if it is present.
