feat: container-info for AWS ECS/Fargate; [5s,1d] guard on central config re-fetch interval

[trentm]

Update elastic-apm-http-client to get these changes.
This also drops using 'container-info' directly in this repo's tests.
Given that the impl in that module and in the http-client might
diverge over time, it isn't necessarily valid to use 'container-info'
here.

Closes: #2914
