🔥 remove internalAnalyticsSubdomain and INTAKE_SITE_FED_STAGING

[BenoitZugmeyer]

Motivation

Two internal SDK behaviors — internalAnalyticsSubdomain init option and the INTAKE_SITE_FED_STAGING special-casing — were workarounds for routing data to Datadog-internal intake endpoints. These are now handled in web-ui using the standard proxy initialization parameter, making them unnecessary.

Changes

• Remove internalAnalyticsSubdomain init option (modified intake host and reversed query parameter order for internal use)
• Remove INTAKE_SITE_FED_STAGING constant and its http-intake.logs.dd0g-gov.com special-casing in buildEndpointHost

Test instructions

No user-visible behavior change. These were internal-only behaviors not exposed to customers.

🔗 RealWorld

[thomas-lebeau]

I'm not sure why we were doing this (found RUMF-1464, but it's not very clear), but this does not seems to be replicated in web-ui.

[BenoitZugmeyer]

Good catch. I'll replicate in web-ui
