If set, when a Samza container starts up, it ignores any checkpointed offset for this particular
input stream. Its behavior is thus determined by the {@link #withOffsetDefault} setting.
Note that the reset takes effect every time a container is started, which may be every time you restart your job,
or more frequently if a container fails and is restarted by the framework.
