Feat /tmp config (#125)
* feat: SAM support for /tmp config (#87) * Add EphemeralStorage field Add EphemeralStorage as a new option when creating SAM templates. Add functionality to transform SAM templates with EphemeralStorage to Cloudformation templates. Add /translate tests for new field * Add EphemeralStorage to global configs * Add EphemeralStorage to global configs * Add testing for functions with intrinsic refs, add EphemeralStorage to versions Co-authored-by: Kevin Weng <[email protected]> * chore: add integration test for /tmp (#101) * Add integration test for /tmp Also edit basic_function_event_destinations template file to avoid deprecated runtime error * Add integration test for /tmp Also edit basic_function_event_destinations template file to avoid deprecated runtime error * Revert changes to template runtime and use getters in test_function_with_ephemeral_storage. Delete duplicated test * Revert runtime changes Co-authored-by: Kevin Weng <[email protected]> Co-authored-by: Kevin Weng <[email protected]> Co-authored-by: Kevin Weng <[email protected]>
