RUMM-3355 Core v2 Configuration

[maxep]

What and why?

Introduce public interface to create a DatadogCore instance.

The Datadog interface will be exposed as DatadogCore in #1335

How?

Default:

import Datadog

Datadog.initialize(
  with: Datadog.Configuration(
    clientToken: "<token>",
    env: "<environment>"
  ),
  trackingConsent: .pending
)

Advanced:

import Datadog

Datadog.initialize(
  with: Datadog.Configuration(
    clientToken: "<token>",
    env: "<environment>",
    site: .us1,
    service: nil,
    bundle: .main,
    batchSize: .medium,
    uploadFrequency: .average,
    additionalConfiguration: [:],
    proxyConfiguration: nil,
    encryption: nil,
    serverDateProvider: nil
  ),
  trackingConsent: .pending
)

Review checklist

• Feature or bugfix MUST have appropriate tests (unit, integration)
• Make sure each commit and the PR mention the Issue number or JIRA reference
• Add CHANGELOG entry for user facing changes

Custom CI job configuration (optional)

• Run unit tests
• Run integration tests
• Run smoke tests

Really good 👍 - nice to see last V1 things disappear.

question/ @maxep What is the plan for getting rid of global .verbosityLevel? Do we have necessary items in the backlog?

[maxep]

Is there a plan to get rid of it? 🤔
Is is used by DD.logger which is also global and since it's for development it makes sense keep it this way, no?

[ncreated]

TBC: sorry, I don't mean "removing it" 🙂. Do we consider attaching .verbosityLevel to SDK core instance, or we want to keep it global? Global would mean seeing logs from all instances of the SDK (even not mine). Whatever we decide it is rather low priority.

[maxep]

Ah! Indeed, it would make sense to prefix the console-log entry with the core instance name. It will require a core-specific logger in the same manner we want Telemetry per core. I will add a ticket for that 👍

Good idea 👍
