<pre>
Name of the span. Must be less than 128 bytes. The span name is sanitized
and displayed in the Stackdriver Trace tool in the
Google Cloud Platform Console.
The name may be a method name or some other per-call site name.
For the same executable and the same call point, a best practice is
to use a consistent name, which makes it easier to correlate
cross-trace spans.

<code>string name = 3;</code>

@param value The bytes for name to set.
@return This builder for chaining.
