This commit makes sure that customizations on the
SessionRepositoryFilter are also applied when the user provides its
own SessionRepository.

Previously, if a health's details contained a key named status (either
because an indicator bean was named statusHealthIndicator or an
indicator added an entry named status to its details) this would
clash with the health's own status as the details were serialized as
siblings of the status field.

This commit updates Health to remove @JsonAnyGetter from getDetails().
This means that all of a Health's details will now be nested within
a separate details field, thereby preventing a possible clash with
the status field.

Previously, if a user's configuration class provided a custom
Validator bean, that configuration class would be initialized very
early so that the Validator could be used to create the
auto-configured MethodValidationPostProcessor. This early
initialization could problems as it may prevent any of the
configuration class's dependencies from being post-processed.

This commit updates the injection of the Validator bean to be lazy,
thereby preventing the creation of the auto-configured
MethodValidationPostProcessor from triggering early initialization.

This commit removes the restriction that was added in 4a61e456 to
prevent / from being used as the management context path when the
management context was not using a different port

The management context path can now be set to / irrespective of the
configuration of the management port. To avoid a possible clash
with the application's welcome page or similar, the links "endpoint"
that is mapping to the management context path is disabled when
the management context path is /.

As part of allowing / to be used as the management context path again,
the handling of endpoint mappings and the creation of paths for
individual operations has been consolidated into a new EndpointMapping
class that is used across the three (MVC, WebFlux, and Jersey)
implementations.

Previously, when DevTools encountered a jar with a Class-Path manifest
attribute that referenced non-existent files, it would log one
message per entry in the attribute that did not exist. While useful
information, this has proven to be too verbose.

This commit aims to strike a better balances by logging a single
message for an entire jar. The message is a single line that
includes the path to the jar with the faulty Class-Path manifest
attribute and the paths of all of the files that do not exist that are
referenced by the attribute.
