Template not found if provider not set.

See discussion here: reverseskate/sparkleformation-workshops#5

Setting the provider in .sfn explicitly resolved the error, so it seems like the default of :aws is not being set correctly in 3.x.

So, if you get an error like:

ERROR: SparkleFormation::Error::NotFound::Template: Failed to locate item named: `example`

Add provider :aws to the credentials block of .sfn

@luckymike this doesnt work when using provider: open_stack I still get the SparkleFormation::Error::NotFound::Template: errors

UPDATE: this was because provider in the template itself was set to heat and not open_stack
