RUMM-2501: Use SDK v2 components in the upload pipeline

[0xnm]

What does this PR do?

This is a transitional PR (some things are not final) which makes the usage of SDK v2 components in the upload pipeline.

Namely we now are using Storage for the batch reads and RequestFactory as well.

Some content inside the implementations of RequestFactory for RUM, Logs and Traces is duplicated, but this is on purpose, because later on these classes will be split into different modules.
