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.

This patch configures the primary components of the amphora to log
to syslog using consistent logging facilities.
By default, user traffic logs will go to LOG_LOCAL0 and the amphora
processes (haproxy, keepalived, etc.) will log to LOG_LOCAL1.

A recent patch[1] (stein master) added the http-reuse option to the
haproxy template for pools. This feature is not available in the HAProxy
version included with CentOS 7, 1.5.x. This could cause an upgrade issue
if the control plane was upgraded to Stein, but the cloud still had older
CentOS based amphora.
This patch corrects that issue by checking the HAProxy version in the
amphora and adjusting the template if it finds an older HAProxy.
This patch also updates the test_health_check_stale_amphora test to
not wait (sleep) for the full heartbeat_timeout.

This patch adds a few optimizations when using the amphora driver.
1. It increases the amp_active_retries from 10 to 30. This increases
the time we wait for nova to mark an instance "ACTIVE". The old default
of 10 was one minute forty seconds, but in some clouds it's been observed
that the nova schedule can get overloaded and take longer than a minute
forty to schedule the instance. Setting this to 30 means we will wait
five minutes for nova to schedule the instance.
2. It enables TCP kernel splicing in HAProxy. This has been shown to
reduce the CPU overhead for very high rate TCP load balancers.
3. Finally it enables "safe" HTTP keepalives on the backend member
connections [1]. This increases the request rate possible while using HTTP
protocol listeners and members.

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.

The common name is used as a file name inside the HAproxy
configuration file. However, a common name can include spaces
and it will result in a configuration file that simply doesn't
work because of the spaces.
The patch changes the functionality so that it instead creates
a SHA1 hash of the certificate and uses that as the file name
to avoid those issues.

Members that were disabled / admin_state_up=False were simply excluded
from the haproxy configuration we pass to the amps. Instead, we should
be creating them in a disabled state, so they return in health messages
as status "maint", and can be marked OFFLINE via the standard health
mechanism, instead of just via override hacks.
This also resolves a bug introduced in an earlier change:
https://review.openstack.org/#/c/567322/

By default haproxy sets the connection limit of any backend to 10% of
the connection limits for all its front-ends. For long-lasting but
low-load connections to a small number of back-end servers through the
load balancer, this means that the haproxy-based back-ends have an
effective connection limit that is much smaller than what the user
expects it to be.
The commit explicitly sets the connection limit for haproxy back-ends to
be equal to that of their front-ends.
