Allow sidekiq_exporter to fail on address in use
What does this MR do?
The !18575 (merged) make the exporters to fail hard, where previously it was allowed to fail softly.
This retains the previous behaviour and properly validates that this is allowed.
This is needed due to lack of mechanism to support shared port
binding when running sidekiq-cluster
mode.

However, it does not fix the underlying problem, but rather retains the previous incorrect behaviour as described by: #5714 (closed)
Does this MR meet the acceptance criteria?
