Inconsistent data for bricks metrics

[VLZZZ]

Problem

GlusterFS volume with 6 bricks (Replicated on 3 nodes).
After resizing the volume using heketi-cli for each node additional brick was added with different size.
Anyway, when exporting metrics there's duplicated brick_pids and no metrics for bunch of bricks in volume.

I though that it's the same problem described in #168 but we use the version with hotfix already.
