Allow specifying the meterNameConsumer for HighCardinalityTagsDetector #4028

Currently, it's not possible to specify the meterNameConsumer, so folks are just left with the default functionality of logging a warning then logging debug messages.

This change would allow for users to specify their own consumer - one use case for this would be to add a new metric that is marked every time there is a metric with high cardinality detected, which could be used for alerting (vs. just looking through logs).

Let me know what you think! Thanks!

@sean-heller Thank you for the PR and sorry to not getting back to you earlier!
I rebased your changes on top of main and modified them a little so that users can specify the way the HighCardinalityTagsDetector is created. This way they can specify any arbitrary parameters used right now and those as well that will possibly be added in the future.
What do you think?
