step-functions fails to deploy with resources decorator and integer values

[saikonen]

Two examples that break with deploying to step-functions:

@resources
@batch(use_tmpfs=True)

@resources(shared_memory=1024)

The culprit is a combination of how compute_resource_attributes tries casting any numeric value to float, and outputting the max as a string, and step-functions relying on the batch implementation, which expects the correct types from the batch decorator for attributes (namely integers)

No issue exists with run --with batch due to the resources decorator attributes going through a json encode/decode before hitting the batch implementation.
