Remove LB_TIMEOUT in favor of lb_build_timeout

Using the CONF.kuryr_kubernetes.lb_build_timeout config option instead
of the LB_TIMEOUT constant allows modifing the LB creation timeout for
different environments where the LB creation time can vary
significantly.

Remove LB_RECONCILE_TIMEOUT as well in favor of a new config option
CONF.kuryr_kubernetes.lb_reconcile_timeout.
