@leonidas , do you mind looking at this PR considering it has lots of changes?

I would like to know the direction where ansible-nvm is moving to regarding nvm install with/without sudo (changed in ahmednuaman@8dfc4f1).
I think it would be better if this role can support nvm installation for both with/without sudo.

Thanks in advance.

This PR has a number of issues:

• nvm_path.stat.exists will stop upgrades
• No defaulting of nvm.profile_file, so the run fails if the example is used and nvm.profile isn't defined
• If node isn't installed, node -v fails, nvm_node_version doesn't get created so nvm_node_version.stdout.find(nvm.node_version) == -1 fails, causing a fatal error.
