Seldon C++ wrapper

[axsaucedo]

Adds C++ wrapper, these two examples show the functionality:

• Single File Build Notebook
• Advanced Buildsystem Override Example

Current features:

• Similar to JNI wrapper leverages the python capabilities through bindings
• Implements protobufs with templates so can be extended to non-SeldonMessage protos
• Passes the bytes as raw and passes a Proto SeldonMessage to the user
• Uses CMake for the core build system
• Provides a structured module that can be installed with utilities
• Includes docker image(s) with builds for dependencies (pybind + protoc)
• Fixes clashes when protocol not dictionary

Outstanding (separate PR):

• Minor optimizations, e.g. avoid passing by value where possible (seems it's possible to pass buffer without copy)
• Benchmarks

This is really amazing @axsaucedo! I've added a couple comments, mainly around docs (there seem to be some missing links). Other than that, this looks great!

[axsaucedo]

Addressed all comments, should be good to go 👍
