feat(standalone): Remove stale time series from windows metrics

[BeegiiK]

Describe the solution you'd like
After developing the initial POC of standalone retina. A few observations were made. After the cache is updated and the metric's time series is made for a particular IP, there is no way this is cleaned up in standard retina and also standalone

In environments where there is a high churn rate of container creation, it's optimal to clean these stale time series up. Update the metric module in the standalone scenario such that the events are sent from the HNS plugin to the enricher then to the metric module. The metric module should be wholly responsible for cleaning these unused time series after the cache removes them
