What Does This Do

This PR reduces verbosity of StatsD connection error.
It keeps full details / stack trace in debug logs.

Motivation

Using read-only file system, users get the following log message which is quite verbose and scary:

[dd.trace 2026-02-13 13:42:08:766 -0500] [dd-task-scheduler] ERROR datadog.metrics.impl.statsd.DDAgentStatsDConnection - Unable to create StatsD client - /var/run/datadog/dsd.socket - Will not retry
