Service responses are not compressed

[achave11-ucsc]

We implemented compression as part of #1910, but it appears to have been disabled again:

Note the accept-encoding header in the request and the absence of the content-encoding header in the response.

[dsotirho-ucsc]

Spike to add reproduction involving curl for both anvilprod and prod. Remember to include gzip in the accept-encoding request header (if it is not already included).

[achave11-ucsc]

Ticket description has been updated with the reproductions for prod and anvilprod using cURL.

[dsotirho-ucsc]

Assignee to consider next steps.

[hannes-ucsc]

I checked, minimum_compression_size is 0 so all responses should be compressed. Assignee to file support ticket with AWS asking why responses are not compressed. Provide @achave11-ucsc's curl repro and a screenshot of the settings of the API used in that repro, showing that minimum_compression_size is indeed 0.

Created AWS Support ticket 172005082100601

As suggested by AWS Support, a Deploy API action was performed, after which the a compressed response can now be produced.

[dsotirho-ucsc]

AWS Support case 172005082100601 resolved with positive feedback.

[hannes-ucsc]

The following is a visualization of the relationships between the TF resources involved. Unlabeled arrows represent dependencies expressed via ${…}. The diagram anticipates the upcoming changes for #6284. The green part is what I hope will fix this issue.

Assignee to verify that, on develop, a change to the minimum_compression_size property of the rest_api resource does not yield a plan that replaces the deployment resource. Assignee to implement the fix and verify that, with the fix in place, such a change would replace the deployment resource.
