Vitaliy Filippov aa1e21dd99 Release 0.6.9 
New features:
- Build Vitastor driver as part of QEMU
- Implement renaming images in CLI (vitastor-cli modify --rename)
- Add vitastor-cli alloc-osd and simple-offsets commands and use them in make-osd,
  thus removing the dependency on etcdctl
- Make monitor remove stale deleted inode statistics from etcd automatically
- Implement OSD address selection from a subnet, thus removing the need to specify
  OSD addresses in startup scripts explicitly

Bug fixes:
- Fix client failover in case of etcd shutdown or crash (make client survive etcd failures)
- Stick to the last live etcd in OSD and mon to prevent random failures when one of etcds is down
- Fix incorrect copying of data from journal to the data device which could lead to data corruption
- Prefer local etcd IPs in OSD
- Remove the total PG count restriction in optimize_change which was sometimes leading
  to inability to redistribute PGs over OSDs
- Fix error response parsing on a failed pg state report
- Fix slow linear writes with RDMA by changing default buffer settings
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix bugs in vitastor-cli create, ls, rm, modify commands

Patch changes:
- Add a patch for libvirt 7.6
- Add patches for QEMU 6.0 and 6.1
- Fix config file path XML location parsing in libvirt patches
- Replace _ with - in QEMU options
- Fix possible 'TypeError' in openstack nova when using Vitastor cinder driver
- Fix possible crashes of QEMU block driver in case of incorrect options

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.

Vitaliy Filippov 891250d355 Implement CAS writes 
From now on, reads will return the server-side object version numbers
and writes and deletes will have an additional "version" parameter
which, if set to a non-zero value, will be atomically compared with
the current version of the object plus 1 and the modification will
fail if it doesn't match.

This feature opens the road to correct online flattening of snapshot
layers and other interesting things.

Vitaliy Filippov 971aa4ae4f Implement RDMA receive with memory copying (send remains zero-copy) 
This is the simplest and, as usual, the best implementation :)

100% zero-copy implementation is also possible (see rdma-zerocopy branch),
but it requires to create A LOT of queues (~128 per client) to use QPN as a 'tag'
because of the lack of receive tags and the server may simply run out of queues.
Hardware limit is 262144 on Mellanox ConnectX-4 which amounts to only 2048
'connections' per host. And even with that amount of queues it's still less optimal
than the non-zerocopy one.

In fact, newest hardware like Mellanox ConnectX-5 does have Tag Matching
support, but it's still unsuitable for us because it doesn't support scatter/gather
(tm_caps.max_sge=1).

Vitaliy Filippov ce777319c3 WIP RDMA support 
Basic naive implementation works, but it's highly non-optimal as
RNR retransmissions occur all the time. RDMA expects the receiver
to always have place for incoming WRs...

Vitaliy Filippov 64eeb79051 Prevent 0.6.x OSDs from talking to 0.5.x 
The new protocol is almost compatible - it has bitmaps, but also it has
a "bitmap_length" field. It's not hard to make 0.5-0.6 OSDs and clients
compatible, but for now I just assume nobody needs it.

If I'm wrong and anybody requests to upgrade their production 0.5.x system
to 0.6.x I'll fix it.
