!htp #18919 #19519 New JavaDSL for Akka HTTP (#20518)

Browse source 
* !htt #18919 #19519 Align Java HTTP server DSL with Scala

This commits replaces the Java HTTP server DSL with a Java-8 centric one
which exposes all scala DSL concepts to be usable from Java, including
custom directives, (un)marshallers, rejections, headers, and type safety
for path and query parameters.

* Add RequestContext and RouteResult to Java DSL
fix websockets
WIP bring java docs up to date.
This applies some updates to the root-level documentation

* [htp] Fix java documentation to correctly mention timeouts

Timeouts are configured the same in Java and Scala. Hence, linking to the
scala docs for timeouts from Java.

* =htc fix optionalHeaderValueByType in Java

* =htt #20200 fix java testkit always using NoLogging instead logger

* +htt actually run new javadsl tests, allow overriding config

* =htt improve javadsl test infra with more details when fails

* =htt fix bug in wrong path matcher exposed

* +htp add missing remaining path matcher

* =htp Java DSL cookie tests fixed

* =htt Java DSL ParameterDirectivesTest fixed

Protect the tweets from scalariform

Incorrect response expectations in cache condition directives spec fixed

* =htt Path directives for Java DSL

* +!htt PathMatchers rewritten, made uniform and tests passing

* Bugfix in java reject and a little test-boyscouting

* Revert "Incorrect response expectations in cache condition directives spec fixed"

This reverts commit cd50e89d45db010309f8249b090ea654ebb11c7a.

* +htc HttpAPIsTest is compile time only, not for running
Also, moved from the client package since not strictly a client test.

SecurityDirectives passing

Two faulty tests and two actual bugs.

Fix for cache condition spec not working

* Not sending in Unit instad of the implicit magnet in the test
* HeaderMagnet now works as expected
* Java API added for - and + on DateTime

PetStore example and test fixed

* Annotations to make marshalling work without default constructor
* Made model class immutable

Incorrect tests fixed

Some scaladoc boyscouting as bonus

* =htt RequestValTest sprinkled out across multiple directive tests

Client ip extraction test with incorrect header name fixed.

* =htt Incorrect CodingDirectivesTest fixed.

* =htt Bugfix for Java Unmarshaller.firstOf and fixes to JavaRouteTest

* =htt MarshallerTest fixed

* Missing seal signature added to JavaDSL
* More consistent (with Scala) test kit setup for Java
* missing Javadocs added
* Thread.sleep in default exception handler removed

* =htt copy directive docs, prepare for finishing it up

* +htt SecurityDirectives.authorize variants and test coverage added

* +htt Custom headers in Java DSL

* =htt WIP on java docs

* +htp add missing parameterOrDefault directive
Fixed a lot of doc warnings

* =htc intense progress on javadsl docs

* =htc #20470 Link to issue about docs and fix compile error
compile, migration guide
don't mima check http-experimental

* =htt Java DSL doc warnings fixed.
Only `Could not lex literal_block` ones left now

* =htc fix mima settings

* =doc fix MethodDirectives doc test with custom method

* =htc fix coding directives spec after bad merge

* =htc fix concat being corresponding to route() in javadsl

* =htt Disable consistency check for route/concat as it fails only on ci server

* !htt Minor fixes to PathMatchers
