Could you add descripion of nvme_img_size in Documentation/runnning-test.md?

I've noticed that tcp and fc of nvme_trtype are not described, but this is a
different topic :)

I read back discurrions on the v1 series, and I'm not sure if it is agreed to
decrease the default size from 1G to smaller value. My understanding is that
Chaitanya's points are:

- Let's keep 1GB default size for consistency for blktests users.
- Introduce nvme_img_size so that those who needs faster test run can
set smaller size.

This change looks weird for me. The required size of TEST_DEV can vary depending
on user's configuration. I think nvme_img_size specify the device size that each
test case prepares, isn't it?
