[Test] Add test to add brick with symlink pointing out

Test case:
1. Create a volume, start it and mount it.
2. Create symlinks on the volume such that the files for the symlink
   are outside the volume.
3. Once all the symlinks are create a data file using dd:
   dd if=/dev/urandom of=FILE bs=1024 count=100
4. Start copying the file's data to all the symlink.
5. When data is getting copied to all files through symlink add brick
   and start rebalance.
6. Once rebalance is complete check the md5sum of each file through
   symlink and compare if it's same as the orginal file.
