feat(statsd): Use symbolicator-style aggregation (#4446)

Replace the existing `MetricsClient` that uses statsdproxy and rely on a modified version of the aggregator used in symbolicator. Note: This PR is a proof of concept and takes a few shortcuts (see below). It therefore should not get merged into a calendar release as-is. 1. Aggregation cannot be disabled. 1. The sample rate is hard-coded to 1. 1. Metrics are not testable using `with_capturing_test_client` for the time being. Might fix getsentry/team-ingest#613
