<pre>
Port override.

When specified, replaces the port part of the task URI. For instance,
for a URI http://www.google.com/foo and port=123, the overridden URI
becomes http://www.google.com:123/foo. Note that the port value must be a
positive integer. Setting the port to 0 (Zero) clears the URI port.

<code>optional int64 port = 3;</code>

@return Whether the port field is set.
