Minimize the cost of checking for api worker exit

A recent change to oslo allows the configuration of the interval
that ProcessLauncher waits between checks of child exit.  The
default interval of 0.01s resulted in the neutron service consuming
unnecessary cpu cycles checking whether api workers had exited (5%
cpu on idle in a VM).  This patch extends the interval to 1s to
minimize the cost of the checks.
