It sounds reasonable to extend the timeout in some cases, but not
without bound. Configurator cannot rely on Enrollee timeout, i.e., there
needs to be something to stop the infinite sequence of adding more time
to the GAS response to cover the cases where the GAS client disappears
from radio range.
