[REQUEST]: Document —id and —replace-token options for enrolling Elastic Agent with Fleet Server

[vishaangelova]

Description

Document the following new options when enrolling an Elastic Agent with Fleet Server:

• —-id (the ELASTIC_AGENT_ID container environment variable)
• --replace-token (the FLEET_REPLACE_TOKEN container environment variable)

Details:

Allows an Elastic Agent to enroll with a defined ID and replacement token so that it can replace an existing Elastic Agent. The original Elastic Agent must have also been enrolled with the same --replace-token or the new Elastic Agnet will not be allowed to enroll if the —-id collides with an existing Elastic Agent.
