Description of problem:
The container_memory_failures_total metric is in the top 10 of metrics with high cardinality. It isn't used in any rule or dashboard. Storing the metric in Prometheus increases memory usage for no benefit.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Open the Prometheus UI, go to the Status > TSDB status page and look at the "Top 10 series count by metric names" section.

Actual results:
container_memory_failures_total is listed.

Expected results:
container_memory_failures_total isn't present.
