Add `ClientHttpRequestInitializer` interface that can be used with any
`HttpAccessor` to initialize each `ClientHttpRequest` before it's used.
This provides a useful alternative to `ClientHttpRequestInterceptor`
when users need to configure things like `HttpHeaders`.

Prior to this commit, a lot of work had been done to prevent improper
use of testing Framework APIs throughout the codebase; however, there
were still some loopholes.
This commit addresses these loopholes by introducing additional
Checkstyle rules (and modifying existing rules) to prevent improper use
of testing framework APIs in production code as well as in test code.
- Checkstyle rules for banned imports have been refactored into
multiple rules specific to JUnit 3, JUnit 4, JUnit Jupiter, and
TestNG.
- Accidental usage of org.junit.Assume has been switched to
org.junit.jupiter.api.Assumptions.
- All test classes now reside under org.springframework packages.
- All test classes (including abstract test classes) now conform to the
`*Tests` naming convention.
- As an added bonus, tests in the renamed
ScenariosForSpringSecurityExpressionTests are now included in the
build.
- Dead JUnit 4 parameterized code has been removed from
DefaultServerWebExchangeCheckNotModifiedTests.

Prior to this commit, the entry set of read-only HttpHeaders lost the
original headers' ordering.
The changes in commit ce7278aaf4 introduced a regression in the read-only
HttpHeaders support. Specifically, the implementation of entrySet() in
the internal ReadOnlyHttpHeaders class converted the original entry set
to an immutable, non-ordered set of immutable entries.
This commit fixes this issue by converting the original entry set to an
immutable, ordered set of immutable entries.

This commit prepends "[{index}] " to all custom display names
configured via @ParameterizedTest.
This provides better diagnostics between the "technical names" reported
on the CI server vs. the "display names" reported within a developer's
IDE.

Prior to this commit, there was no way to replace the Set-Cookie header
via MockHttpServletResponse. Specifically, an invocation of setHeader()
for the Set-Cookie header resulted in an additional Set-Cookie header
instead of replacing the existing one, which is in violation of the
contract for javax.servlet.http.HttpServletResponse.setHeader(...).
This commit refactors the internals of MockHttpServletResponse to ensure
that an existing Set-Cookie header is overwritten when set via an
invocation of setHeader(). This commit also verifies the expected
behavior for addHeader() and addCookie() with regard to multiple cookies.
Closes gh-23512
Due to a bug (or "unintentional feature") in JUnit 4, overridden test
and lifecycle methods not annotated with @Test, @Before, @After, etc.
are still executed as test methods and lifecycle methods; however,
JUnit Jupiter does not support that. Thus, prior to this commit, some
overridden test and lifecycle methods were no longer executed after the
migration from JUnit 4 to JUnit Jupiter.
This commit addresses this issue for such known use cases, but there
are likely other such use cases within Spring's test suite.

The use of LinkedCaseInsensitiveMap, going back to 3.0, makes it
unnecessary to iterate over keys which can cause
ConcurrentModificationException.

This commit migrates parameterized tests in spring-core using the
"composed @ParameterizedTest" approach. This approach is reused in
follow-up commits for the migration of the remaining modules.
For a concrete example, see AbstractDataBufferAllocatingTests and its
subclasses (e.g., DataBufferTests).
Specifically, AbstractDataBufferAllocatingTests declares a custom
@ParameterizedDataBufferAllocatingTest annotation that is
meta-annotated with @ParameterizedTest and
@MethodSource("org.springframework.core.io.buffer.AbstractDataBufferAllocatingTests#dataBufferFactories()").
Individual methods in concrete subclasses are then annotated with
@ParameterizedDataBufferAllocatingTest instead of @ParameterizedTest or
@Test.
The approach makes the migration from JUnit 4 to JUnit Jupiter rather
straightforward; however, there is one major downside. The arguments
for a @ParameterizedTest test method can only be accessed by the test
method itself. It is not possible to access them in an @BeforeEach
method (see https://github.com/junit-team/junit5/issues/944).
Consequently, we are forced to declare the parameters in each such
method and delegate to a custom "setup" method. Although this is a bit
cumbersome, I feel it is currently the best way to achieve fine grained
parameterized tests within our test suite without implementing a custom
TestTemplateInvocationContextProvider for each specific use case.
Once https://github.com/junit-team/junit5/issues/878 is resolved, we
should consider migrating to parameterized test classes.

Added support for status codes that do not occur in HttpStatus in
DefaultClientResponseBuilder and made ClientResponse::statusCode
ClientHttpResponse::getStatusCode @Nullable.

The isJavaIdentifier check is not really required, but also seems
intuitive for variables to be Java identifier-like. This commit relaxes
the constraint a bit by also allowing "-".

Prior to this commit, the `header(String, String)` method in the
ServerHttpRequest.Builder API actually added a header value instead of
setting or overriding a header value. Since this conflicted with the
stated behavior in the Javadoc as well as the original intention of the
method, we have decided to introduce an overloaded variant
`header(String, String...)` which accepts a var-args list of header
values to set or override.
In addition, this commit deprecates the existing `header(String, String)`
method for removal in Spring Framework 5.2.
In order not to be a breaking change for custom implementations of the
builder API, this commit implements the new `header(String, String...)`
method as an interface `default` method, with the intent to remove the
default implementation in Spring Framework 5.2
