Previously, the configuration class that produces the ErrorPageFilter
bean was an inner class of SpringBootServletInitializer. As a result,
whenever SpringBootServletInitializer was subclasses, the
ErrorPageFilter would be used. This adversely affected applications
running as an executable war file and those deployed to a container
with error page filter registration disabled.

This commit makes ErrorPageFilterConfiguration a top-level class so
that it is no longer always found via SpringBootServletInitializer.
The test that verifies that error page filter registration can be
disabled has been updated to more accurately simulate the behaviour
when an application is deployed as a war to a standalone container.
A test that mimics the behaviour of an application run as an
executable war has also been added.

The additional configuration for an `HazelcastInstance` will be removed
in 2.0. This commit makes sure that the property is deprecated in 1.5

If the Princial is a Spring Security Authentication object and the
request doesn't have the right roles, check the authorities.

  Polish "Allow loader.path to refer to nested jars"
  Allow loader.path to refer to nested jars

Closes gh-8334
Closes gh-8465

Previously, each entry in loader.path could only refer to a standard
jar file. Refering to such a jar would add all of the classes in
the root of the jar to the class path.

This commit adds support for referencing a directory within a jar file
that contains one or more nested jars. For example:

$ java -jar -Dloader.path='jar:file:./lib.jar/!BOOT-INF/lib' my.jar

This will add all of the classes in all of that jars in the
BOOT-INF/lib directory of lib.jar to the class path.

As of Hazelcast 3.7, the bootstrap is pretty slow by default due to the
networking discovery. This commit disables both TCP/IP and multicast
discoveries.

  Tighten up PropertiesLauncher's contract

See gh-8346
Closes gh-7221

The main changes are:

- Switch to `loader.properties` instead of `application.properties`
- Search for `loader.properties` in `loader.home` as well as in
  the classpath
- Placeholder replacements in MANIFEST.MF (using `loader.properties`
  or system/env vars)

Closes gh-8346

This commit makes sure that if `local.mongo.port` is set, a `MongoClient`
on the embedded MongoDB instance is created. When an embedded instance
is detected, only the `host` property is used and the `uri` is ignored if
set.

This makes sure that the auto-configured `MongoClient` automatically
switches to the embedded server, even if a production uri has been
specified.
