[Replay] Make replay sample rates top-level config

[mydea]

Problem Statement

Currently, replay sample rates are configured directly in the integration:

Sentry.init({
 sampleRate: 0.5,
 tracesSampleRate: 0.1,
 profilesSampleRate: 0.25,
 integrations: [
 new Replay({
 sessionSampleRate: 0.1,
 errorSampleRate: 1.0
 })
});

This is inconsistent.

Solution Brainstorm

We want to move these options to the top level:

Sentry.init({
 sampleRate: 0.5,
 tracesSampleRate: 0.1,
 profilesSampleRate: 0.25,
 replaysSampleRate: 0.5,
 replaysOnErrorSampleRate: 1.0,
 integrations: [
 new Replay()
});

The goal is, for now, to deprecate the "old" options directly on Replay and remove them in a later release.

Steps

• Add new top-level options
• Deprecate configuration in integration
