Support AWS Lambdas ephemeral storage setting (#1120)

[gbartosz]

Description

Since march 2022 AWS allows for setting custom ephemeral storage size for Lambda (a storage mounted in a /tmp directory). Boto also supports this setting since v1.21.26. This PR extends zappa_settings.json with ephemeral_storage key with default value of {"Size": 512}.

Can you add a testcase confirming that the given cli value is properly changed and doesn't exceed the max configurable ephemeral_storage value? (throws proper error

Hi @gbartosz @elip-OE @mdw123 what is the status of this PR? I'm happy to merge it if we get the PR comment by @monkut in there. (I've removed the next-release-candidate label because it's not a priority for the upcoming release, but we can get it done in the next or the one after, if this is solved 🤩)

Hi @hellno ! I'm really want this feature to be released, but I can't write a testcase. It would be great if someone in the team can do it instead.

In case this feature is not in priority, you can add an extra conf that goes as-is into the aws API, which will be fully flexible.

Hi @hellno @monkut , I'm also quite keen on this feature. Given this PR seems to have gone stale, i've opened a new PR with the requested tests and validation here: https://github.com/zappa/Zappa/pull/1259

@Meepit Thanks for the PR update, closing this one.
