Description

This PR updates reqwest dependency version from 0.11.18 to 0.12.2 to address frequent disconnections and connection reset errors.

The major here is that we use actix_web along with reqwest. With reqwest releasing 0.12.0, http crate version was bumped from 0.x to 1.x while on actix_web v4.5.1 it is still on version v0.2.9. This version mismatch is what is handled here in this PR.

Also, in webhook.rs, it is not possible to directly convert headers that we get from reqwest to match with actix_web unless actix_web updates http version to 1.x. Also, since reqwest does not support HttpRequest explicitly, we cannot directly use that either which led to manual conversion. (Open for discussions on this)

reqwest changelog can be found here and notable breaking changes can be found here

After today's discussions, it has been decided to better wait before getting this PR merged as actix_web has an open PR that updates http crate version to 1.x from 0.2.9 (which might take some time).

Once that is done, it will be easier for us to update the dependencies all together (actix_web, http and, reqwest) to their latest versions.

With that said, I'll be closing this PR to avoid any conflicts or confusion. I'll be raising yet another PR on behalf of this (just to keep the history clean) addressing the above mentioned changes.

I do not think this will ever be looked upon since:

• we are moving away from using reqwest in many places
• refactor that is being done
