faet: add rabbitmq cluster_name

[abhishuraina]

Description

Add a rabbitmq.cluster.name resource attribute, scraped from GET /api/cluster-name (same pattern as the existing GetQueues/GetNodes/GetExchanges) — no new connection or credentials needed.

Resource attribute, disabled by default — same convention as rabbitmq.vhost.name.
Applies to all three resource types (collectQueue/collectNode/collectExchange) — unlike vhost, cluster name isn't vhost-scoped, so it belongs on node metrics too.

Link to tracking issue

Fixes #50168

Testing

CGO_ENABLED=0 go test ./... (pass)
CGO_ENABLED=0 go vet ./... (pass)
git diff --check (pass)
go test -race ./... could not run on the local Windows image because its installed 32-bit C compiler cannot build 64-bit race binaries; upstream CI should run the race job on supported runners.
