Release 0.6.12

etcd connection stability, clang & elbrus support

- Fix build under CLang and Elbrus LCC compilers, making Vitastor compatible
  with Elbrus CPUs :)
- Completely fix the bug where OSDs didn't connect to peers and incorrectly marked
  PGs as incomplete
- Limit I/O depth for deletes the same way as for small writes. Makes OSD crashes
  with "Assertion failed: sqe != NULL" during image deletion go away
- Fix a very old, but rare, journaling bug (credits to https://github.com/mirrorll)
- Fix flushing of unclean journaled objects leading to OSDs sometimes hanging
  after failover in EC setups (bug was introduced in 0.6.7)
- Fix several problems that could prevent smooth operation of a Vitastor cluster
  under the condition of partial etcd failure:
  - OSDs could randomly fail due to too strict error handling
  - New clients and OSDs could be unable to start because of the lack of retries
  - CLI could fail some commands because of the lack of retries
  - Monitor could stop receiving state updates because of the lack of websocket pings
- Fix monitor being unable to rebalance PGs after a downscale of pool pg_size (3->2)
- Exit with failure when trying to nbd map or benchmark a non-existing image
- Use HTTP keep-alive for etcd connections
- Allow to configure etcd request timeouts and retries
- Allow to configure NBD timeout, max devices and partitions, and set default to
  up to 64 devices with up to 3 partitions each
