Make sample env file optional

[tayden]

When using the plugin like this:

// ...
new DotenvPlugin({
  path: './.env',
}),
// ...

with no sample .env file location defined, the plugin throws a no such file or directory, open './.env.default' error. Defining the sample file location fixes the problem.

It would be nice if providing a sample path was optional.

Maybe you can try using mine which does just that: https://github.com/mrsteele/dotenv-webpack

Thanks for the suggestion @tayden. The reason a sample.env is required is it uses dotenv-safe as a warning system to alert which keys are required. This is useful to ensure you have all the correct keys set, and finding that earlier than later is a good thing.

At this stage I prefer it to be required, but I'd be happy to make it optional if others feel this might be beneficial.
