Reduce latency of first ad request

Overview
The time it takes for the first ad request to be made. This is the interval from
page load until the first ad request is issued.
Recommendations
This metric is not indicative of a specific issue. It should be used to help
identify areas for improvement and track that improvement over time.
The goal here is to reduce the time it takes for the first ad request to be
made. Ensuring that other, more specific audits are passing should have a major
impact on this metric. In particular, audits affecting
tag load time and
latency of first ad request (from tag load) are
likely to affect this metric.
This metric identifies "first ad request" as the earliest recorded request to
one of:
