Currently the spring-grpc-core imposes an opinion on Netty.
The core module should not have an opinion, but rather the
starter enforces the opinion.
Also, makes spring-grpc-core optional in the autconfigure
module as the autoconfigure will eventually be moved into
Spring Boot and at that time everything is optional.

The exception handler interceptor has to be called first so that
it can handle exceptions thrown by other interceptors. Tests up
to now didn't assert that (they focused on exceptions thrown
in services).
This commit improves the GrpcChannelFactory createChannel API by
introducing `ChannelBuilderOptions` that can be specified during
channel creation.
Additionally, concrete Netty channel factory implementations have
been added as well as adding type to the GrpcChannelBuilderCustomizer
which helps match customizers to channel factories.
If the user wants a second port for gRPC that should be possible
(and was the only way with the old ecosystem projects). This change
adds a webflux sample and support for
spring.grpc.server.{servlet,reactive}.enabled to be explicitly
"false" to disable the embedded services.
N.B. embedded services are not yet supported in webflux so the flag
has no effect, except to disable gRPC completely if it is "true".
This commit adds the implementation to the previously added skeleton
ActuatorHealthAdapter. On a configurable schedule, the adapter takes
a configured list of Actuator health indicators and gets their current
status and maps it into the gRPC HealthStatusManager.
