Include the config-loader again

[lholmquist]

After talking with @lance, we decided it might be better to have the config loader integrated back into this library.

I think if no config is passed, then it just does the default stuff(calls config-loader), but if a config is passed in, then it will use that instead

I think i was trying to be to smart with this #5

[lholmquist]

This will change the method signature from func(config, settings) to just func(settings)

if you still want to pass in a custom config object, add it to settings.config, likewise, if you need to override something in the config loader, pass that in with settings.openshiftConfigLoader

also going to raise the node version needed to 8.x

Once this change is in, we will probably bump to 1.0.0 since it is a breaking change

[lholmquist]

@tavogel wanted to give you a heads up

[tavogel]

Thanks. This will be breaking as we don't use local configuration but as long as we can still override it should be ok

[lholmquist]

@tavogel yea, you can override using settings.config = {...}

[lholmquist]

@tavogel if you wanted to give the new version a try, i created a "canary" version as 0.12.0-0
