Create a custom exporter that ingests logs before shipping to Loki

• What is the current behavior?
  Right now, we use Loki to query and display metrics using log aggregation. However, this could be a bottleneck at scale depending on the amount of logs we are ingesting.

One can argue we're not really using the right tool for our use case either which is to show metrics. Log aggregation may be overkill for this.

Instead, what if we built a customer exporter (ingestor) that scrapes and outputs time-series metrics based off each log? This will allow for a really responsive metric querying and visualization, while still relying on Loki for indepth log analysis.

Notes

Need to baseline the performance and determine if the benefits are worth it.

How much can an ingestor/exporter scale ingesting the logs?
Can we use grok_exporter ?
Is this an anti pattern to what Loki is suppose to be? Or can we use both? One for metrics, one for indepth debugging.
Does promtail/loki already support something like this so we don't have to spin up another process

Instead of wasting a lot of write IO to parse logs, we're descoping this. I worked with Jorge from Poktscan on the next GeoMesh update which should include a lot more verbose metrics being emitted. This along side a general-purpose HAProxy / Nginx dashboard should be more powerful then our existing solution. See below

Loki can still be continued to be used for log aggregation and tracing, but we'll stop using them for visualization purposes.
