gluster-block: Initial Commit

gluster block storage CLI.

As of now, gluster-block is capable of creating tcmu based gluster
block devices, across multiple nodes.

All you need is a gluster volume (on one set of nodes) and tcmu-runner
(https://github.com/open-iscsi/tcmu-runner) running on same(as gluster)
or different set of nodes.

From an another (or same) node where gluster-block is installed you
can create iSCSI based gluster block devices.

What it can do ?
--------------
1. create a file (name uuid) in the gluster volume.
2. create the iSCSI LUN and export the target via tcmu-runner in
multiple nodes (--block-host IP1,IP2 ...)
3. list the available LUN's across multiple nodes.
4. get info about a LUN across multiple nodes.
5. delete a given LUN across all given nodes.

$ gluster-block --help
gluster-block (Version 0.1)
 -c, --create      <name>          Create the gluster block
     -v, --volume       <vol>            gluster volume name
     -h, --host         <gluster-node>   node addr from gluster pool
     -s, --size         <size>           block storage size in KiB|MiB|GiB|TiB..

 -l, --list                        List available gluster blocks

 -i, --info        <name>          Details about gluster block

 -m, --modify      <RESIZE|AUTH>   Modify the metadata

 -d, --delete      <name>          Delete the gluster block

     [-b, --block-host <IP1,IP2,IP3...>]  block servers, clubbed with any option

Typically gluster-block, gluster volume and tcmu-runner can coexist on
single set of nodes/node or can be split across different set of nodes.

Install:
-------
$ make -j install (hopefully that should correct you.)

Points to remember:
------------------
1. setup gluster volume
2. run tcmu-runner service
