Problem:
-------
1. Currently, each cli command take ~5 secs for execution. The Maximum
latency is due to initializing a glfs object (glfs_init() and friends).
2. OOM kills due to glfs_fini() leaks (~10MB per object)
Solution:
--------
Caching bipasses glfs_init() calls from the very next command, as in the first
command it goes via the glfs_init route, since there will be cache miss.
Hence with caching cli command on a local machine should take ~1 sec.
ATM, the cache query looks at the volume name only, as the host name will be
localhost in our case and transport will be tcp 24007 always.
The default cache capacity is 5 i.e there can be a max of five glfs entries in
the cache, anything more will lead to release of least recently used object.
This way, if there are <= 5 volume in use for block, there will be no
glfs_fini() calls, hence no leaks, no OOM's.
The next patch will help in making cache capacity configurable.

This is how cli response looks like, on supplying '--json*' flag to cmd-args:
$ gluster-block create block-test/sample-block1 ha 1 localhost.localdomain 1GiB --json
(or)
$ gluster-block create block-test/sample-block2 ha 1 localhost.localdomain 1GiB --json-spaced
{ "IQN": "iqn.2016-12.org.gluster-block:681af106-85f1-4a02-a122-57c80903458c", \
"PORTAL(S)": [ "localhost.localdomain:3260" ], "RESULT": "SUCCESS" }
$ gluster-block create block-test/sample-block3 ha 1 localhost.localdomain 1GiB --json-plain
{"IQN":"iqn.2016-12.org.gluster-block:0fdf6647-57f2-477f-8dd4-54a3de06e410",\
"PORTAL(S)":["localhost.localdomain:3260"],"RESULT":"SUCCESS"}
$ gluster-block create block-test/sample-block4 ha 1 localhost.localdomain 1GiB --json-pretty
{
"IQN":"iqn.2016-12.org.gluster-block:e92ca4a0-5325-4c4b-a407-9e75790e4c7f",
"PORTAL(S)":[
"localhost.localdomain:3260"
],
"RESULT":"SUCCESS"
}

Till now we had simple makefile for checking dependencies and building.
Using libtoolz will give more control on dependency checks and
flexibility.
This patch also introduce rpm build feature.
Compiling:
$ ./autogen.sh
$ ./configure
$ make -j
$ make install
Building RPMS:
$ make rpms
Running:
$ systemctl start gluster-blockd.service
Using CLI:
$ gluster-block help
