Update `UserInfoTokenServices` to use a PrincipalExtractor interface
to extract the principal.

Fixes gh-5186

Update HttpEncodingProperties to offer explicit `force-request` and
`force-reponse` properties in additional to the existing `force`
property.

Closes gh-5459

Update EndpointWebMvcAutoConfiguration so that ApplicationFailedEvents
cause the management context to close.

Prior to this commit if an application failed to start (for example
because `server.port` was already in use) the management context would
remain open and the application would not exit.

Fixes gh-5388

Update MockitoPostProcessor to filter bean names that match
`ScopedProxyUtils.isScopedTarget` from the candidates list.

Fixes gh-5724

* pr/5972:
  Fix Mockito tests to align with name and comments

Fixup Mockto tests where the test implementation didn't align with the
name of the test or the test Javadoc.

Closes gh-5972

Update ResetMocksTestExecutionListener to only attempt a mock reset when
a singleton has actually been created.

Fixes gh-5870

Update TestRestTemplate so that it no longer directly extends
RestTemplate. Prior to this commit it was possible that TestRestTemplate
could interfere with user defined RestTemplate beans.

TestRestTemplate offers the same methods as RestTemplate so should be
a drop-in replacement. If access is needed to the actual underlying
template the `getRestTemplate()` method should be used.

Fixes gh-5915

Hibernate 5.1 logs an ugly but benign exception when using an in-memory
HSQL database when it tries to drop a non-existent constraint.

This commit changes the Spring Data REST sample to use H2 rather than
HSQL. This prevents the unwanted exception from occurring as Hibernate's
H2 dialect returns false from dropConstraints.

Instead of using a @Bean, it is better to use an opaque factory
for an internal dependency that users are not going to want in
the context. OAuth2RestTemplate is a common enough bean type that
creating on in autoconfig makes it hard for users to add their own
for business use.

See gh-5967

* pr/5975:
  Remove unchecked casts

Closes gh-5975

Improve the message thrown when a @PropertyMapping is used in
combination with a @Component to include the actual annotations that
are causing the problem.

Fixes gh-5897

Deprecate `PropertiesConfigurationFactory.setProperties()` since it was
only being used in tests.

Fixes gh-5930

Fixes gh-5933

The `if` in registerSpies() is not required as it's covered by the
Assert check.

Closes gh-5889

Closes gh-5883

Closes gh-5934

This commit removes the creation of a `@Primary` `OAuth2RestTemplate`
and updates the documentation accordingly.

Once #5507 is implemented we could revisit this area to provide a way for
users to easily create such a bean.
