Merge pulsar-functions dist package into pulsar binary distribution (#…

…1332)

* 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
