#### Is this a new chart
No
#### What this PR does / why we need it:
This PR contains updates to the helm chart for upcoming LP.
Specifically, we update the client to export `http.route` in HTTP
metrics to light up the transactions UI, disable JVM stats tracing since
we do not export that data and modify the collector to synthesize
service<>service entity relationships.
