Loggregator Message Reliability Rates in CF253

Adam Hevenor

The Loggregator team has seen an increase in the rate of `doppler.shedEnvelopes` and `doppler.dropped` metrics starting in the CF253[1] deployment. The doppler.dropped increase has been attributed to a metric calculation bug, but the shedEnvelopes is something we are seeing other evidence of in the form of flaky tests, and community feedback.

If you are seeing message relaibility issues in your deployment please contribute to the github issue[2].
