Support for Ephemeral Storage size in config parameters

[ojhilt]

Now that lambda supports changing the ephemeral storage size of a lambda function, in much the same way as memory size etc.. is there any plan to add this as a supported configuration parameter?

This will be really useful! I have lambdas that do some light video processing, and need to download them so /tmp gets filled up quickly.

Right now I have to use the AWS CLI in a script to update after deploying.

If you are interested, I have published a fork of chalice with support for configuring ephemeral storage.

It's possible to override it by using the deployment with AWS Cloudformation, and the extras.json https://aws.github.io/chalice/topics/cfn.html#template-merge
