glusterfs-profiler: Add text mode support.
glusterfs-profiler works in text mode by default now. This allows it to run on systems which don't have matplotlib installed. Modes can be selected using: -m graph - Graphical mode -m text - Text mode (default) Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 268 (Add timing instrumentation code) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=268
