Enrollment handing for containerized {fleet}-managed agents

Beginning with version 8.18, for {fleet}-managed {agents} that run in a containerized environment (including Docker, Kubernetes, and others), enrollment handling is managed as follows: * **Enrollment Verification:** The {agent} checks the stored enrollment conditions within its container environment and re-enrolls only when necessary. * **Unenrollment Handling:** If an {agent} is unenrolled via the {fleet} UI but still references a valid enrollment token provided through environment variables, it will automatically re-enroll on the next container restart. In versions lower than 8.18, an unenrolled agent remains unenrolled and does not re-enroll, even if a valid enrollment token is still available.
