[rozo] Add volume outputs

* Output providing the volume list:
```sh
- vid 1:
  - {bfree: 0, blocks: 0, bsize: 8192}
  - cid 1:
    - {free: 0, size: 0}
    - sid 1: {free: 0, host: ' localhost', size: 0}
      sid 2: {free: 0, host: ' localhost', size: 0}
      sid 3: {free: 0, host: ' localhost', size: 0}
      sid 4: {free: 0, host: ' localhost', size: 0}
    cid 3:
    - {free: 0, size: 0}
    - sid 1: {free: 0, host: ' localhost', size: 0}
      sid 2: {free: 0, host: ' localhost', size: 0}
      sid 3: {free: 0, host: ' localhost', size: 0}
      sid 4: {free: 0, host: ' localhost', size: 0}
- vid 2:
  - {bfree: 0, blocks: 0, bsize: 8192}
  - cid 2:
    - {free: 0, size: 0}
    - sid 1: {free: 0, host: ' localhost', size: 0}
      sid 2: {free: 0, host: ' localhost', size: 0}
      sid 3: {free: 0, host: ' localhost', size: 0}
      sid 4: {free: 0, host: ' localhost', size: 0}
```
* output providing details about a particular volume:
```sh
- cid 1:
  - {bfree: 0, blocks: 0, bsize: 8192}
  - sid 1: {free: 0, host: ' localhost', size: 0}
    sid 2: {free: 0, host: ' localhost', size: 0}
    sid 3: {free: 0, host: ' localhost', size: 0}
    sid 4: {free: 0, host: ' localhost', size: 0}
- cid 3:
  - {bfree: 0, blocks: 0, bsize: 8192}
  - sid 1: {free: 0, host: ' localhost', size: 0}
    sid 2: {free: 0, host: ' localhost', size: 0}
    sid 3: {free: 0, host: ' localhost', size: 0}
    sid 4: {free: 0, host: ' localhost', size: 0}
```
[rozo] Add export.py, and define output

Here is an example of the export listing output:
``` sh
- eid 1:
  - {hquota: '', md5: '', root: /srv/rozofs/exports/export_1, squota: '', vid: 1}
```
[rozo] add export stat output

```sh
- eid 1:
  - {bfree: 12790866, blocks: 12803668, bsize: 8192, ffree: 1242286, files: 2}
- eid 2:
  - {bfree: 6395433, blocks: 6395433, bsize: 8192, ffree: 1242286, files: 0}
```
[rozo] correction in 'remove_export' used to rely on rpc (now it relies on ExportdStat
Merge branch 'feature/rozo_new_parser' of http://github.com/rozofs/rozofs into feature/rozo_new_parser
[rozo] fix bug when 'make' and merge ordered output with messy output

After merging Pierre's and my work, a bug appeared when *make* saying profile.i
couldn't be found. No surprise here as this file was removed in the last few
commits.
Corrections involve cmake/setup.py.in and manager/rozofs/core/platform.py.

Further bugs appeared as my version use the previous "puts(obj)" definition.
Pierre redefine this function for the output to be sorted. Temporary correction
define both functions. Must be fully sorted in next corrections.
