Add support for gzip compression

[brianneisler]

This is a Feature Request

Description

It would be great to support gzip compression for all http traffic including requests and responses.

Use-cases

• Compress http requests and allow for the event-gateway to decompress the request
• Compress responses from the gateway

Concepts

• Allow for accepted compression types to be configured at the gateway level (during startup time) in the order that they are preferred.
• Allow for allowed compression types to be configured on a per subscription basis.
• Gateway should inspect the Accept-Encoding header to determine which types of compression are supported

Examples

Sending a compressed request

curl --request POST \
  --url http://127.0.0.1:4000/ \
  --header 'content-type: application/json' \
  --header 'content-encoding: gzip' \
  --data ./file.gz

Accepting a gzip response request

curl --request GET \
  --url http://127.0.0.1:4000/ \
  --header 'Accept-Encoding: gzip, deflate, br' \

response headers

Content-Encoding: br

Hello @brianneisler, do we know what is the status for this feature or if this was already added to the current Serverless framework?

Hey @xoscar, AFAIK it's not been added to the framework as in the first place it has to be added to the Event Gateway. Right now it's hard to tell what is the deadline for that feature.
