Rename ~/.auth to ~/.profitbricks-auth

[vain]

Pull request for #53.

~/.auth is a very generic file name. At the very least, there should be a prefix such as profitbricks-, which is implemented in this PR.

Hello @vain and thank you for the PR. I agree this is a change that is much needed. The only problem I foresee is breaking backward compatibility with existing installations. Users will have to reconfigure their credentials.

We should either add backward compatibility (using .auth if present) and release as a minor version update or allow only .profitbricks-auth and release as a major version update.

We already have a NodeJS and CLI update for ProfitBricks Cloud API v4 in the pipeline; ETA two or three weeks which will be a major version release. Are you able to wait for that release to include this feature? If so, then I proceed to merge this into master.

Hi,

yeah, sure. This is not a pressing issue. We can surely wait a couple more weeks. :-)

What about a simple check in profitbricks-cli, which checks, if .auth is available or not and if, then it simply should rename it to .profitbricks-auth? :)

Here is a very simple example in bash:

if [[ -f .auth ]]; then
	mv .auth .profitbricks-auth
fi
