This commit enables compatibility build against Spring Framework 5.
The Velocity and Guava support that are deprecated in the 1.x line have
been removed and few other classes contain minor change to comply to non
backward compatible changes in Spring Framework 5.
This commit also switches the required java version to 8.

Rework commit 4a69755b to remove the need for the ApplicationInfo class.
The updated code now uses the auto-configuration class to compute a
default persistence unit root location
Closes gh-6635
Due to the layout format change in 1.4, Spring Framework is no longer
able to compute a default persistence unit root URL. If a Spring Boot 1.4
application has JPA but does not have any entity, the application started
from a fat jar now fails with a quite cryptic exception.
This commit introduces `ApplicationInfo` as a general replacement for
the `ApplicationArguments` and `Banner` singleton beans that
`SpringApplication` registers on startup. `ApplicationInfo` also defines
the detected "main" `Class` that can be used to compute a last resort
URL that makes sense.
If such bean is available, `EntityManagerFactoryBuilder` now sets the
default persistence unit root location, preventing Spring Framework to
attempt to resolve an unknown location. Note that in our case the
persistence unit root location is actually useless: given the way the
persistence unit is created, nothing actually uses it but Hibernate, as a
compliant JPA provider, has to make sure this setting is set to a valid
URL nevertheless.

The upgrade to Hibernate 5.2.0.Final has provide to be too
problematic to live with. It requires Java 8, is incompatible with
a number of other projects in the Hibernate ecosystem, and it's
unclear for how long it will be maintained. We'd previously used
Hibernate 5.1.0.Final but its maintenance is also unclear with
Hibernate 5.1.1.Final being more than 3 months overdue.
This commit drops back to Hibernate 5.0.9.Final. This has a few
advantages:
- It's Java 7 compatible
- It's had some time to mature and should be reasonably free of
regressions for those moving from 4.3.x
- It's used in both Wildfly and JBoss EAP so there's a fair chance
that it will continue to be maintained.

This commit changes the default version of Tomcat to 8.5.3 while
also retaining support for Tomcat 8.0 and 7.0. The main difference
in 8.5 is that the ServerSocketFactory abstraction that allowed the
TrustStore and KeyStore to be configured programatically no longer
exists. This logic has been replaced with the use of a custom URL
protocol (springbootssl) that provides access to the key store and
trust store of an SslStoreProvider. In addition to working with 8.5,
this approach has the advantage of also working with 8.0 and 7.0.

This commit removes HSQLDB dependency from Batch Starter as most apps
that use Spring Batch will prefer to use a RDBMS of their choice to store
batch metadata.
Additionally, explicit spring-jdbc dependency has been replaced with JDBC
Starter dependency.

As of Spring Framework 4.3, spring-aop now embeds the classes from the
aopalliance:aopalliance jar. This means that the transitive dependency
on aopalliance:aopalliance is redundant and it can be excluded.

This commit upgrades to MongoDB 3. Dependency management has been added
for the new and preferred mongodb-driver artifact. The starter has
been updated to use this new artifact rather than monogo-java-driver.
Dependency management for mongo-java-driver has been retained to avoid
causing problems for people who have declared the dependency explicitly.
The auto-configuration for Embedded Mongo has also been updated to
use 3.2.2 by default.
Closes gh-3011
"Starter POM" is a confusing term as it implies the starter may be a
POM while it's actually a jar artifact like any other dependency. To
reduce the confusion (especially in the way such starter should be
declared in the build), the term Starter POM has been renamed to Starter.
Closes gh-5966
This commit deprecates the `ws` starter in favour of a new `web-services`
starter. A deprecation warning auto-configuration has also been added to
the ws starter.
