This commit switches off the auto-configured JspServlet's
development mode by default. Development mode is then switched on
when DevTools is on the class path.

ErrorPageFilter contained an optimisation for looking up the path
of an error page by exception type. For cases where there was no
mapping for the type of the exception that was thrown but there
was a mapping for one of its super classes, it was intended to
speed up the lookup. Unfortunately, there was a bug in the
implementation which meant that the optimisation had no effect.
Analysis with JMH reveals that for an Exception with a deep type
hierarchy, such as Spring Framework's UnsatisfiedDependencyException,
and an error page mapping for Exception, searching up the hierarchy
until a mapping is found takes 0.0000001s. With the same mapping,
a lookup for Exception takes 0.00000001s, i.e. it's 10x faster.
The optimisation, when correctly implemented, brings the time for
UnsatisfiedDependencyException down to 0.00000001s and into line
with a lookup for Exception. However, the amount of time involved is
so small compared to the overall time spent processing a request that
the added complexity of the optimisation is not justified.

Every classes that's compiled by Kotlin is annotated with
kotlin.Metadata. The attributes of this annotation always differ so
if they are used in the cache key, context caching will effectively
be disabled.
This commit updates the key used by ImportsContextCustomizer to
ignore the kotlin.Metadata annotation. Additionally, to align with
with Java where annotations in java.lang.annotation are ignored,
annotations in kotlin.annotation are also ignored.

URL.getContent() is shorthand for URL.openConnection().getContent().
It creates an InputStream that isn't explicitly closed. This means
that a file handle remains open until the URLConnection is garbage
collected. This can lead to the process exceeding the limit for open
files.
Previously, LaunchedURLClassLoader was using getConent() when
proactively defining a package for a class that is about to be loaded.
getContent() was used to access nested jar files to check if they
contained the package and, if so, to retrieve the jar's manifest.
In place of using getContent(), this commit uses JarURLConnection's
getJarFile() method which provides access to the JarFile without the
unwanted side-effect of opening an input stream.

Cassandra sometimes takes a long time when dropping the test keyspace.
This results in the test failing due to an exception being thrown.
This commit attempts to make the tests more robust by catching and
logging any exceptions thrown during server cleanup.
Previously, a relative PID folder was not handled correctly when
running stop, status, or force_reload. This meant that a service
could be started when configured to use a relative pid file, but
then could not be stopped.
The PID folder should be treated as relative to the service's jar
file. This commit updates stop, status, and force_reload to push the
jar file's directory so that this is now the case for those three
commands.

Update EndpointHandlerMapping so that it can be subclasses easily.
Subclasses can override the `path` that is used to map the endpoint,
allowing different mapping strategies to be used.
See gh-7108
Introduce a new NamedMvcEndpoint interface which can be used when an
MvcEndpoint also has a logical name. Existing MvcEndpoints have been
reworked to implement the NamedMvcEndpoint interface.
Fixes gh-7156
Remove EndpointWebMvcManagementContextConfiguration `disabled` logic
since the configuration should even be processed when the management
port is `-1`.
Closes gh-7154
