modify: add support for one way authentication

2017-05-02T09:38:51+00:00

This patch introduce or rather implement modify command for
enabling authentication for block devices.

The schematics of authentication setting, looks like

$ gluster-block modify block-test/sample-block auth enable --json-pretty
{
  "SUCCESSFUL ON":[
    "192.168.0.105"
  ],
  "IQN":"iqn.2016-12.org.gluster-block:8917def2-e90d-4406-8c9c-6d06b6851bbe",
  "USERNAME":"8917def2-e90d-4406-8c9c-6d06b6851bbe",
  "PASSWORD":"a3e75362-a446-45af-98d0-a1ed7e10d7f0",
  "RESULT":"SUCCESS"
}

As an effect it brings changes in 'info' command response, note PASSWORD

$ gluster-block info block-test/sample-block --json-pretty
{
  "NAME":"sample-block",
  "VOLUME":"block-test",
  "GBID":"8917def2-e90d-4406-8c9c-6d06b6851bbe",
  "SIZE":1073741824,
  "HA":1,
  "PASSWORD":"a3e75362-a446-45af-98d0-a1ed7e10d7f0",
  "BLOCK CONFIG NODE(S)":[
    "192.168.0.105"
  ]
}

The schematics of auth disabling, looks like
$ gluster-block modify block-test/sample-block auth disable --json-pretty
{
  "SUCCESSFUL ON":[
    "192.168.0.105"
  ],
  "IQN":"iqn.2016-12.org.gluster-block:add99c38-3c14-42d7-bf23-7d02f388e1e7",
