Vitaliy Filippov ce5b6253ab Make OSDs stick to the last successful etcd address
Previously OSDs were selecting a new random etcd from the cluster
on every request so they were failing randomly when part of etcds was down

Vitaliy Filippov 8398ad0117 Fix #36 - Fix old version data sometimes overriding new version data
Reproduction case:
- v3 = (offset 4kb, length 16kb)
- v2 = (offset 24kb, length 16kb)
- v1 = (offset 16kb, length 16kb)
- At the third step it was inserting 16..24kb instead of 20..24kb

Vitaliy Filippov 660c3f7b0d Change default RDMA settings to 128x 129K buffers
129K to leave extra space for the header

The problem with 8x 1M buffers is that the following happens with,
for example, 2 OSDs and 4M T1Q1 write:
- Server posts 8 receives
- Client posts 8 sends
- WRs are processed by the RDMA stack, but the OSD doesn't have the time
  to handle them and doesn't refill buffers
- Client posts 1 more send
- RNR retransmission happens and performance drops to zero

Overall it seems that RDMA support should be reworked to use real 'RDMA'
operations i.e. operations writing into remote memory. This has an
additional advantage of avoiding a copy at the receive side of the OSD.

Vitaliy Filippov 7eabc364bf Release 0.6.7
- Implement CLI commands for listing, viewing I/O statistics, creating,
  snapshotting, cloning, resizing and modifying images. All these operations
  are covered by 3 commands: ls, create, modify
- Implement an important fix to prior OSD set tracking for PGs. The previous
  version had an issue which could lead to data loss due to an OSD with older
  copy of the data thinking it has the newest copy
- Fix I/O statistics aggregation in the monitor
- Several minor fixes for Cinder driver
- Fix QEMU driver to be compatible with QEMU 2.x > 2.0
- Fix stalls sometimes possible in configurations without immediate_commit due
  to insufficient amount of automatic internal fsync operations
- Add `vita` alias for `vitastor-cli`

Vitaliy Filippov aa436027c8 Report pg/history from OSD on every degraded activation
Required to prevent data loss due to activation of an OSD with older data
when PG OSD set change doesn't occur. I.e. fixes the simplest case:
- Run 2 OSDs with 1 PG
- Start writing into the PG
- Stop OSD 2
- Stop OSD 1
- Start OSD 2

After this change the PG will refuse to start after the last step.
