Don't tell Qpid to reconnect in a busy loop.

Fix bug 929784.

Don't set any of the reconnect timing options unless they have been set
in the configuration.  Setting them all to zero puts Qpid in a mode
where it will reconnect in a busy loop.  By not setting these unless a
non-zero value has been provided, Qpid goes back to its default
behavior, which is to use an exponential backoff on reconnect attempts
(after 1 second, then 2, 4, 8, etc).
