Move integrations to main repo + new Ktor client integration

[serras]

This PR does a few things (sorry, I forgot to switch branches).

It moves the Jackson module from arrow-integrations repo into the main repo, which makes it easier to release in the future. Alongside it reorganizes the repo, moving all the integrations modules (Retrofit, Jackson, kotlinx.serialization) into a new integrations folder.

Alongside those, it adds a new integration with Ktor in the form of a client plug-in. It does the same as the built-in HttpRetry but using our Schedule and CircuitBreaker.
