[PATCH] UBUNTU: SAUCE: ubuntu_nbd_smoke_test : break up nbd-client, commands

[Sean Feole]

Please see LP# 1947031 for more context.

It was found that due to 2x nbd-client commands being re-run immediately 
after one
another caused a race condition. The sleep command allows smaller 
instance types to
ensure the block device is completely free and clear after the first 
request, thus,
not interfering with the second.

This has been tested and has resolved issues in Azure Cloud.
