* Add convenience method to start timer without key
It is probably common that there is no need to allow different timers
that send the same message, and this makes that more convenient to write.
Updated one method to gather feedback, if we like the change I can apply
it to the others as well.
* Add alternative to all typed timer API's
Update java/scaladoc, update tests
Not updated classic actors and FSM API's
* some messages from ActorSubscriber were also used in other places,
so moved those to impl.ActorSubscriberMessage
* WatermarkRequestStrategy used by SourceRefImp, so moved there
* TestAppender interaction with LoggingEventFilter
* TestAppender plays the same role as classic TestEventList
* replace Sl4jLoggingEvent.java
* include MDC in testkit.LoggingEvent to allow for custom filter
testing MDC
* fix tests
* fix log events in BehaviorSetKit, using SubstituteLogger
* MDC in EventSourcedBehavior
* using raw MDC to set the persistenceId and persistencePhase fields
* avoid access to MDC ThreadLocal if log isn't used
* Automatically enable eventStream Slf4jLogger for Typed (PR #27583)
* amend the ActorSystem config on startup when config akka.use-slf4j=on
and akka-slf4j in classpath
* akka.use-slf4j is defined in akka-actor-typed reference.conf
* also enable the Slf4jLoggingFilter automatically
* remove config in tests
* Include actor path as akkaSource in MDC (PR #27587)
* move logger init to ActorContextImpl since not specific to untyped (ActorContextAdapter)
* careful to not access MDC ThreadLocal if logging isn't used (per message)
* MDC is cleared (if used) from aroundReceive in ActorAdapter after processing each message
* also changed MDC for EventSourcedBehavior to rely on context.log and the outer MDC.clear()
* just removing the MDC values is not enough because the empty Map remains in the ThreadLocal
* Optimization of MDC interceptor (PR #27610)
* Extension methods to Logger as workaround for overload and varargs problem (PR #27605)
* "ambiguous reference to overloaded definition" for 2 arg method
* varargs not supported for primitive types
* providing extension methods info2 and infoN (and friends) via implicit class LoggerOps
as more convenient workaround for these problems
* New API for Typed LoggingEventFilter (PR #27611)
* builder style
* will make it easier to add more conditions
* all conditions are AND:ed together which makes it easier to define custom filters
* simplifies the implementation as a bonus
* javadsl
* use new api in all tests
* leeway setting
* verify that occurrences = 0 works
* use javadsl in two tests
* change interceptLogger, and some other feedback
* Testing utility to silence logging until failure (PR #27588)
* Logback appender that captures all log events and can flush them
later to other appenders
* LogCapturing mixin for ScalaTest that flush the captured logging events
when a test fails. Also clears the captured events after all tests.
* Configuration in logback-test.xml
* log capturing for JUnit tests too, using TestRule
* Silence initial setup logging from Logback
* make LogCapturing public
* use LogCapturing in all tests
* aside from multi-jvm, and a few extending AkkaSpec, so far
* a few doc tests needed debug level
* mention in migration guide
* rename setLoggerClass to setLoggerName
* check for logback dependency to give nicer error message
* fix filterKeys, deprecated in 2.13
* because static methods are resolved by looking at extended class too,
and that results in ambigious method clash with existing create in
ActorMaterializer
* Untyped to classic naming convention #24717
* Added entry of naming convention change to migration docs.
* Rename `toUntyped` to `toClassic` in adapters
* Replace MaterializerSettings with Attributes #25559
* Field access to settings deprecated to make stages use attributes instead
* Internal stages updated to use attributes
* Docs on ActorMaterializerSettings updated to recommend away from using it
* Verify all stages stopped after each testcase in FlowGroupBySpec
* Subscription timeout attributes merged into one
* Move messages from DeviceProtocol to Device (in .java)
* rename Message to Command
* rename createBehavior to create
* rename message handle methods to onX
* private constructor
* get rid of DeviceManagerProtocol too
* rename Message to Command
