Vitastor

Implement a storage plugin for Proxmox. Now you can use Vitastor with Proxmox!
Implement vitastor-cli df (pool space usage statistics) command
Add glob pattern support for vitastor-cli ls
Fix several bugs in other CLI commands (resize, create --parent, modify --readonly)
Use 512 byte logical block size in QEMU driver by default (and thus don’t require to set it in QEMU options)

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

Build separate packages for OSD, monitor, client, C header, fio and QEMU drivers instead of one package which included everything

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
