Add the ability to configure the tx_timer timeout and add a bottom

the new default when the iothread is enabled.  Thanks,

As a further thought, maybe it would help to have a
separate namespace for unsupported, developer-only parameters.
Thoughts?

We already have an undocumented one, just prefix with 'x-' to indicate that it's experimental.

Anthony Liguori
