* fix localrun and add tests

* minor fix

* Improving localrun for functions

* improving impl and adding tests

* add missing modules

* moved all windowing related code into its own submodule.

* added pom

*Motivation*

There are a few shaded modules introduced when functions was introduced.
They are not needed anymore. We should remove them.

*Modifications*

Remote those unused modules.

* [java-11] Compilation fixes

* Runtime fixes

* Fix dependencies for discovery service

* Fixed json mapper provider in new jersey

* Fixed license files

* Added hk2 dep to proxy

* Added hk2 deps to pulsar-client-admin as well

* added missing jar in license file

* More license fixes

* removing metrics module from functions

* removing other references ot Prometheus metrics server

* removing references to pulsar-functions-metrics

* fix unit tests

* revert test change

* cleaning up and improving function metrics

* slight refactoring

* fix unittest

* moving pulsar-spark tests into its own module

* Added SecretProvider and SecretProviderConfigurator interfaces and some implementations

* Added appropriate documentation

* Added validation logic to config provider configurator

* Added more comments

* Took feedback into account

Signed-off-by: NSijie Guo <sijie@apache.org>

* Removed internal shading

* Fixed handling of IllegalArgumentException in ZK client wrapper

* Fixed tests with real ZK server

* Removed multifunction.jar from sources

* Added test dependency

* Removed test scoped dependency on test examples

* Removed tests

* Refactor pulsar function admin api location

* Move pulsar functions dependency version to root pom and remove duplicated license headers

This addresses some comments in pulsar functions PR #1314

* shade worker

* Fix broken master

* Upgrade the bookkeeper storage client dependency to the official bookkeeper version

This removes the temp dependency in `pulsar-functions-instance`

* set `protobuf2.version` in pulsar-common

* provide a shaded worker

* include worker dependency at broker

* Embeded function worker at broker

* rename 'function worker' to 'functions worker'

* add "--no-functions-worker" for pulsar-client-cpp tests

* Integrate function cli into pulsar-admin cli

- rename `pulsar-client-tools-shaded` to `pulsar-client-admin-shaded-for-functions`, because this module is used by functions only to avoid protobuf conflicts
- move protobuf3 references to Utils, so it won't be referenced out side of pulsar-functions
- integrate function cli into pulsar-admin cli

* Merge pulsar-functions dist package into pulsar binary distribution

* Fix license header issues

* Fixed ZK cache test exectutor configuration.

Fixes #1338

- Remove function-composition

- the package will be generated under `dist/target/`

Refactored instance related stuff into instance as well as rejiggered utils into its own module (#248)

* Refactored instance related stuff into instance as well as rejiggered utils into its own module

* Discard empty files

because pulsar-client is using patched protobuf, while dlog/bookkeeper/functions uses same proto3.

- move cli related classes to a CLI module
- use pulsar-client (shaded jar) for runtime
- use dlog (unshaded jar) in worker

* Move worker module out of runtime module

* Fix license header issues

* Provide a jmh benchmark to benchmark thread container

* Rebased to latest master

* revert the scripts

* Create pulsar-functions module (#1)

* Create pulsar-functions module

* rename `sdk` package to `api`

* Added the first cut of the Java interface for Pulsar functions (#2)

* Refactored serialization/deserialization into an interface

* Split functions module into api/runtime/api-examples

* Move `org.apache.pulsar.functions.api` package from runtime to api package

- introduce a `fs` package for function state related classes
- add `FunctionConfig` for user defined function configurations
- add `CmdFunctions`: it takes a yaml file and also command parameters

* Create pulsar-functions module

* rename `sdk` package to `api`
