Can't use credentials for authentication

[burhancoulibaly]

This module doesn't except credentials for authentication only keyfilename this can be fixed by adding

options.credentials = options.credentials || process.env.GCS_Credentials || null; on line 23

and
if(options.keyFilename != null){
try{
this.gcStorage = new Storage({
projectId: options.projectId,
credentials: options.keyFilename
});
}catch(error){
console.log(error);
}
}else if(options.credentials != null){
try{
this.gcStorage = new Storage({
projectId: options.projectId,
credentials: options.credentials
});
}catch(error){
console.log(error);
}
} or something similar to this starting on line 37

I ran into this issue trying to host an app on Heroku. Without this added if the user inputs google credentials (client_email, and private_key) and not the keyfilename the google-auth-library module looks to the environment to get GOOGLE_APPLICATION_CREDENTIALS and returns an error saying that the it was unable to load default credentials, pretty much ignoring the client email, and private_key credentials. I have had no luck trying to add my google auth json file as a config var to Heroku and found that this is an alternative solution.
