Returns {@code true} if any Subject's {@code Session} may be used to persist that {@code Subject}'s state,
{@code false} otherwise. The default value is {@code true}.
<p/>
<b>N.B.</b> This is a global configuration setting; setting this value to {@code false} will disable sessions
to persist Subject state for all Subjects that do not already have a Session. It should typically only be set
to {@code false} for 100% stateless applications (e.g. when sessions aren't used or when remote clients
authenticate on every request).
