Different versions of Docker produce different responses when building
and tagging an image. On CI, a response with a stream like
"Successfully built 185991ffe24a" followed by a response with a
stream like "Successfully tagged spring-boot-it/centos:6.9-a23bced6"
is received. By default, for the building of an image to be considered
successful, the Docker Java client requires the stream for the last
response item to contain "Successfully built". This means that, on the
CI server, it incorrectly believes that the building of the tagged
image has failed.
This commit uses a custom BuildImageResultCallback that doesn't
require the last response to be the one that has a stream containing
"Successfully built". Instead, it looks back through the error-free
responses (newest to oldest) looking for one with a stream containing
"Successfully built".
CentOS 5 was declared EOL in March 2017 and yum on longer works
out of the box. 6.9 is the latest release of CentOS 6. Tests for
CentOS 7 have not been added as it uses systemd rather than SysVinit.

This commit refactors the `ServerProperties` property keys and
introduces a separate "server.servlet" namespace to isolate
servlet-specific properties from the rest.

Previously, a relative PID folder was not handled correctly when
running stop, status, or force_reload. This meant that a service
could be started when configured to use a relative pid file, but
then could not be stopped.
The PID folder should be treated as relative to the service's jar
file. This commit updates stop, status, and force_reload to push the
jar file's directory so that this is now the case for those three
commands.
Closes gh-7092
Previously, tags were used for CentOS and Ubuntu images that may
change over time. This commit updates the Dockerfiles to use fixed
base images. For Ubuntu, a fixed tag is available. For CentOS we
have to resort to using the digest.
