Nginx client request body is buffered to a temporary file

[zKoz210]

This fixes warnings from nginx and creating temporary files on disk

[warn] 46#46: *133550 a client request body is buffered to a temporary file /var/cache/nginx/client_temp/0000011816, client: 172.30.0.1, server: , request: "POST /api/53/envelope/?sentry_key=-&sentry_version=7&sentry_client=sentry.javascript.vue%2F7.80.0 HTTP/1.0", host: "-", referrer: "-/"

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. and is gonna need some rights from me in order to utilize my contributions in this here PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.

This change will put pressure on memory on instances, where lots of requests are received simultaneously.

Hm, you're right. It may be good to reduce the value of this to something like 32k. Would that still fix the issue for you @zKoz210?

[zKoz210]

64k was perfect for me, after that the warnings disappeared
