This commit aligns our dependency management for GemFire with the
version used by the version of Spring Data GemFire that we currently
depend upon.

Previously, some dependency management that was added (see #2884) to
work around problems with GemFire 8.0’s dependencies; specifically it
depended on different versions of org.eclipse.jdt.core.compiler:ecj and
xml-apis:xml-apis. The different dependency versions appear to no
longer be a problem with 8.1 so this dependency management is now
redundant and has been removed.

This commit adds support for automatically configuring Spring Session.
In a web application when both Spring Session and Spring Data Redis
are on the classpath, Spring Session's Redis Http Session support
will be auto-configured. The max inactive interval for Redis-backed
sessions can be configured via the environment using the existing
server.session-timeout property.

Migrate `spring.view.prefix` and `spring.view.suffix` to
`spring.mvc.view.prefix` and `spring.mvc.view.suffix` respectively. The
former properties are still handled in a backward compatible way and are
defined as deprecated in the meta-data.

Closes gh-3250

Previously, DefaultRepositorySystemSessionAutoConfiguration would
read the local repository configuration from settings.xml, but did
not perform any property interpolation. This would leave placeholders
such as ${user.home} as-is and result in the use of the wrong
location. To address this, the code that reads settings.xml has been
updated to provide the current System properties as a property
interpolation source.

RepositoryConfigurationFactory configures the local repository as a
"remote" repository when the local repository location has been
overridden. This allows spring grab to copy dependencies from the
local repository into the grab output location (configured via the
grape.root system property) rather than having to download them again.
This logic did not consider the customization of the local repository
location via settings.xml so the dependencies would be downloaded again.
To address this, RepositoryConfigurationFactory has been updated to
attempt to use the location configured in settings.xml, before falling
back to the default location.

The logic that reads settings.xml has deliberately been duplicated. It
could have been extracted into a separate class, but this is only a
temporary measure until gh-3275 is tackled. Duplication was deemed
preferable to adding a new public class in 1.2.x that we’d then want to
remove in 1.3.

Improve SpringApplicationAdminMXBean to expose additional information:

* Whether the application uses an embedded container
* The properties exposed by the `Environment`

This allows to know if the application is web-based and the HTTP port
on which it is running.

Closes gh-3067

Previously, the actual HTTP port on which a web application is running on
was only exposed in tests. This commit makes sure to provide that feature
regardless of the environment so that applications can know on which port
they are actually running on.

If there are several containers, each is exposed via the namespace of
their respective application context.
