A subdirectory is no longer created by default. Therefore, a server restart uses same directory for both data and metadata. Note, that the rootdir can be cleaned with the -c argument. For multiple daemons on one machine, the new argument --rootdir-suffix can be used which creates a subdirectory within the rootdir with a user-defined name. This also allows restarting multiple daemons on one node without losing data.

Client now reads host file to determine auto_sm and RPC protocol

Reformatted code w.r.t. unifying code styles as of the official
CPPCoreGuidelines by Stroustrup and Sutter

Port is only meaningful for some of the communication protocols. For
instance psm2 is not using it at all.

Port can be still specified using the --listen,-l flag:

Example:
```
gkfs_daemon --listen "localhost:1234"
```

A new cli parameter `--listen`,`-l` allow to specify binding address/interface

RPC port can now be configured at runtime through `--bind-port` command line argument.

For some comunication layers an out of band communication is required for putting in place the specific protocol handshake.

In those case a shared lookup file could be used to distribute deamon's endpoints information to all the clients.

This file need to resides on a shared filesystem and can be specified using the new CLI parameter `--lookup-file`.

gid and uid metadata fields have never been used and can be removed
safely

the functionality wasn't used at all and it will be implemented later
with a different approach

Data operation has been grouped under a ChunkStorage class
that will manage all the data backend operations.

The instance of this object is stored into the ADAFS_DATA sigleton.
