Update dependency management to exclude commons-logging and add
an enforcer rule to spring-boot-samples to try and prevent unwanted
commons-logging dependencies from sneaking back in again.

Prior to this commit any application configured to write
`META-INF/build-info.properties` could trigger unexpected application
restarts. The problem is particularly prevalent when using Eclipse M2E in
combination with Maven's `spring-boot-maven-plugin` `build-info` goal
and Gradle's `springBoot` `buildInfo()`.
Closes gh-7002
Previously, when a Tomcat connector failed to start it was assumed that
the failure was due to the port being in use and a PortInUseException
was thrown. Unfortunately, this assumption doesn’t always hold true.
For example, a Tomcat connector will also fail to start when its using
SSL and the key store password is wrong. This could lead to incorrect
guidance from the PortInUseFailureAnalyzer indicating that a port clash
had occurred when, in fact, it was the SSL configuration that needed to
be corrected.
Unfortunately, Tomcat only tells us that the connector failed to start.
It doesn’t provide access to the exception that would allow us to
determine why it failed to start. This commit updates the embedded
Tomcat container to throw a ConnectorStartFailedException in the event
of a connector failing to start. A new failure analyser,
ConnectorStartFailureAnalyzer, has been introduced to analyse the new
exception and offer some more general guidance.
Closes gh-6896
The default behaviour is unchanged, but it is useful for some applications to be
able to bind without placeholder resolution (e.g. to prevent exposing system
environment variables, if the bound object is being sent over the wire).
