Subject: thin-arbiter : Provide scripts and service file to start thin-arbiter
 process

1 - setup-thin-arbiter.sh
To setup directory path for thin-arbiter. This is the path where replica id
file will be placed and used by TA process.
By default it will be /mnt/thin-arbiter. It is better to use default path
and once set it should not be changed.

2 - gluster-ta-volume.service
This is the Unit file used by systemd to start and keep the thin-arbiter
process running.

3 - thin-arbiter.vol
This is the default volume file for thin-arbiter. It will be used to start
thin-arbiter process. This should not be modified by user except the
directory path which can be modified using [1].

Change-Id: I68f2164f24adfa326c1d1a7a98c6ac4ff04ed553
fixes: bz#1579786
