Run on AWS Lambda managed EC2 instances?

[TomNicholas]

This announcement from AWS is interesting.

https://aws.amazon.com/blogs/aws/introducing-aws-lambda-managed-instances-serverless-simplicity-with-ec2-flexibility/

tl;dr: You can now launch tasks on EC2 instances through a Lambda-like serverless interface.

Running Cubed on EC2 serverlessly like this is appealing, because you could:

• Get access to larger memory instances - this could be interesting in conjunction with In-memory rechunk #502
• Use ARM chips, which are much cheaper - this gives you one of the main advantages of Coiled
• EC2 in general is cheaper than Lambda (though I haven't checked the prices of this announcement)

Support for this could go in Lithops or in a dedicated Cubed executor.
