This commit moves the existing Spring MVC Mustache support to its own
`servlet` package and adds a new one under `reactive` for the WebFlux
web applications.
New `MustacheView` and `MustacheViewResolver` types resolve and render
Mustache views for WebFlux applications.
Since this templating engine is now supported by two flavors of Spring
web apps, the `spring-boot-starter-mustache` does not depend anymore on
the `spring-boot-starter-web` one: it's up to the developer to add the
relevant starter `web` or `webflux` to their application.
Fixes gh-8648
Add autoconfiguration to bootstrap MongoDB Reactive Streams driver
components, reactive Spring Data MongoDB and reactive repositories. Add
bean dependency processor for flapdoodle so embedded MongoDB instances
are configured before bootstraping the reactive MongoDB client.
Add Spring Data MongoDB Reactive starter with blocking and non-blocking
dependencies. MongoDB requires a separate driver that is used in the
`ReactiveMongoTemplate` while `MappingMongoConverter` (shared amongst
blocking/reactive Template API) requires the blocking driver to resolve
DBRefs.

Update Spring Integration metrics support since Spring Integration
`4.3.6`+ no longer needs `spring-integration-jmx` enable
`MessageChannel`, `MessageHandler` and `MessageSource` metrics.
- Add `IntegrationManagementConfiguration` conditional auto-configuration
to provide `@EnableIntegrationManagement` when JMX is `enabled` or there
is no `IntegrationManagementConfigurer.MANAGEMENT_CONFIGURER_NAME` bean.
By default this bean doesn't exist and you explicitly should declare it
(e.g. via `@EnableIntegrationManagement`) if you would like to collect
metrics. At the same time Spring Integration enables it when JMX
management is present (that is a purpose of that new
`IntegrationManagementConfiguration`)
- Change `SpringIntegrationMetricReader` to read metrics from the
`IntegrationManagementConfigurer`, not `IntegrationMBeanExporter`
- Change `PublicMetricsAutoConfiguration` to register
`IntegrationManagementConfigurer.MANAGEMENT_CONFIGURER_NAME` bean if
not present. Since we are here in `actuator`, therefore we are
interested in the metrics for SI as well.
- Since we don't need JMX for the metrics any more, remove SI-JMX
dependency from the `spring-boot-starter-integration`.
- Remove `IntegrationManagementConfiguration` modification from the
`integrationMbeanExporter()`, since that looks like mutation of an
external object, when end-user would prefer their own options.
Therefore we don't need `ObjectProvider<IntegrationManagementConfigurer>`, too
- Add missed `MessageSourceMetrics` gathering for the
`SpringIntegrationMetricReader`
