Code review comment for lp://qastaging/~chad.smith/charms/precise/block-storage-broker/bsb-retries-on-volume-create-and-attach

[1] I would increase the retry time to 30s, 5s seems too frequent.

Just two minor thing to fix. I tested both the unit tests and deploying on openstack, all worked great.

Thanks for the contribution. Hopefully this will make it more stable. If not, we can easily increase the retry count as well.

I like it.
