Issue: SPR-13999

In order to align with the relaxed programming models of TestNG and the
upcoming JUnit 5 (with regard to method visibility), this commit
removes the requirement that @BeforeTransaction and @AfterTransaction
methods must be 'public'.

Issue: SPR-13997

This commit introduces a SpringRunner extension of
SpringJUnit4ClassRunner that is intended to be used as an 'alias' for
SpringJUnit4ClassRunner, primarily in order to simplify configuration
of JUnit 4 based integration tests.

Developers can use this alias as follows:

    @RunWith(SpringRunner.class)
    public class MySpringIntegrationTests { ... }

Includes support to declare expecations should occur multiple
times as well as in any order.

MockRestServicesServer now supports an expect variant that accepts
a range of expected count of executions.

Issue: SPR-11365

The MockRestServiceServer builder now has an option to plug in a
custom RequestExpectationManager.

Issue: SPR-11365

MockRestServiceServer now provides static methods for builder-style
creation of MockRestServiceServer. This includes an option ignore
the order of declaration expected requests.

Issue: SPR-11365

This commit factors out the logic to declare and manage expectations
including matching them to requests and verifying at the end behind
a commong abstraction.

MockRestServiceServer delegates to the new abstraction and is no longer
aware of how that's done. There are two implementations, one for
ordered and another for unordered expectation.

Issue: SPR-11365

Before this commit RequestMatcherClientHttpRequest served both as
API to define request expectations, i.e. ResponseActions, as well as
the implementation of ClientHttpRequest representing actual requests.

DefaultResponseActions replaces this class as a simple holder of
expected requests and mock responses. MockRestServiceServer is then
responsible to match request expectations and create a mock response.

Issue: SPR-11365

This commit allows to specify the request body type in order to
serialize generic types with a GenericHttpMessageConverter if
needed.

* pr/934:
  Fix Format-string method arguments

Closes gh-934

The CORS pre-flight request matching logic for all request conditions
was added (in 4.2) to RequestMappingInfo. However the logic for
default handling of all HTTP OPTIONS requests for 4.3 unintentionally
overrode some of the pre-flight request handling thus causing issues.

This commit moves CORS pre-flight matching logic into each respective
RequestMethodCondition implementations so each has to consider in one
place what happens for pre-flight and for all other requests.
