This commit changes the solr health indicator to request the status of
all available cores, rather than invoking a generic ping on the admin
handler.
Recent versions of Solr now have a ping handler per core and the general
admin handler is gone, leading to incorrect health status. For backward
compatible reason the `solrStatus` attribute is kept to `OK` if all cores
are running properly (that's actually `0` behind the scenes).

As part of the upgrade, this commit removes the use of any API that
has been deprecated in 2.9. This includes the config props endpoint's
use of SerializationFeature.WRITE_NULL_MAP_VALUES. This has been
replaced with configuring serialization inclusion to only include
properties with non-null values. This means that all null-valued
properties will no longer be serialized, not just those that are an
entry in a map.

Restructure `org.springframework.boot.autoconfigure.web` to better align
with the new package structure in `spring-boot`.
Auto-configuration is now split into client, servlet and reactive
sub-packages. In addition a new `http` package now handles common
HTTP concerns.
Fixes gh-8616
Rework `org.springframework.boot.context.embedded` to relocate classes
to `org.springframework.boot.web`. Packages are now organized around
the following areas:
Packages for shared concerns, for example the `WebServer` interface
to start/stop a server and the common configuration elements:
- org.springframework.boot.web.context
- org.springframework.boot.web.server
Servlet specific packages:
- org.springframework.boot.web.servlet.server
- org.springframework.boot.web.servlet.context
- org.springframework.boot.web.servlet.filter
Reactive specific packages:
- org.springframework.boot.web.reactive.context
- org.springframework.boot.web.reactive.server
Embedded server implementations (both reactive and servlet):
- org.springframework.boot.web.embedded
In addition:
- Rename `EmbeddedServletContainerFactory` to `ServletWebServerFactory`
to align with the `ReactiveWebServerFactory`.
- Rename `EmbeddedWebApplicationContext` to
`ServletWebServerApplicationContext` and
- Rename `EmbeddedReactiveWebApplicationContext` to
`ReactiveWebServerApplicationContext`.
- Add checkstyle rules to restrict imports.
- Fixup all affected code to use the correct imports and local names.
Fixes gh-8532
