[wic][PATCH] wic tests: Add docstrings to test methods

[Ed Bartosh]

Docstrings make nosetests output more clear:

Test wic create --help ... ok
Test wic --help ... ok
Test wic list --help ... ok
Test wic create directdisk providing all artifacts. ... ok
Test wic create directdisk --image-name core-image-minimal ... ok
