Template was using timeout value instead of delay value.
Also clean up redundant values in the templates (things like retry and
delay_before_retry only need to be specified once at the top level).

UDP members didn't support monitor_address and monitor_port parameters.
Setting those values didn't have any effects.
This commit enables the support of both parameters.

Load balancers with multiple listeners, running on an amphora image
with HAProxy 1.8 or newer can experience excessive memory usage that
may lead to an ERROR provisioning_status.
This patch resolves this issue by consolidating the listeners into
a single haproxy process inside the amphora.

1. Remove 'inhibit_on_failure' option from realserver configuration block.
Then when the member is failed which means the MISC_CHECK is failed,
the amp agent can not get the member info from kernel ip_vs file, and
it will return status DOWN to health manger, then the member status
will be ERROR, and its associated pool and loadbalancer will be in
DEGRADED status.
Alternative:
Using notify_up/notify_down to write the status into a member specific
file, then we can read the member status from that file directly.
