variables and paths have been updated to the new project name
ADAFS -> GKFS

`gflags` is an optional dependency of RocksDB, it is used only for cli
tools that we don't use.

Mercury now support shared memory autorouting.

A single margo instance can be initialized and it will handle both
shared memory communication and remote ones.

If the endpoint of the RPC is local mercury will automatically use
shared memory.

Since there is only one margo instance all the duplicated code for
rpc/ipc have been unified and simplified considerably.

------

The way in which client contact the server has changed.

 - Server initializes its own margo instance and generate the endpoint
communication string using `HG_Addr_self`.
 - This endpoint description string is written on the pid file
 - When the client library loads it will fetch the server endpoint
description from the pid file and will use that to contact the server.

The new docker folder will host all the docker image files.
At the moment there is only one image file that allows to build a container based on CentOS 7 that provides a complete build environment for ADAFS. It is bundled with all the required dependencies, both from system repository and the ones that need to be compiled from source. It also provide a suitable compiler (gcc 7.2.1) for later use.

This container can be use as developing environment as well as the base for other images. For instance we can use it to build a container that provide the ADAFS daemon.
