Omnidirectional release

New features:

• Support handling TCP I/O in simple separate io_uring-based I/O threads - may increase linear performance to 7-8 GB/s
• Experimental internal etcd replacement - antietcd
• Monitor now has a built-in Prometheus exporter
• Added a reference Grafana dashboard
• Implement vitastor-cli osd-tree and ls-osd commands
• Implement vitastor-cli modify-osd command
• Implement vitastor-cli pg-list command
• Implement VitastorFS defragmentation
• Implement basic node.js binding (not published on npm yet)

Changes:

• Make immediate_commit=all the default everywhere to match default vitastor-disk behaviour
• Make pool-create error message more obvious and add details to it
• Set default etcd_ws_keepalive_interval to 5 seconds (speedup client etcd failover)
• Support OpenStack 2023.2 in Nova and Cinder drivers/patches
• Add patches for libvirt 10.x
• Add patches for QEMU 8.2 and 9.0
• Implement internal restart / run_forever in monitor
• Some source tree refactoring - sources are now moved into subdirectories, monitor is now split into multiple files
• Add vitastor_c_inode_get_immediate_commit in vitastor_c client library
• Make vitastor_kv.h header public

Bug fixes:

• Fix total statistics usec/count/bytes not being reported when delta (bps/iops/lat) is zero
• Prevent infinite loop in NFS on files with incorrect metadata pointing to an empty volume
• Fix READDIR offsets (cookies) in VitastorFS sometimes leading to client infinite loops when reading a directory
• Fix a rare infinite loop during OSD journal flushing (OSD hanging and eating 100 % CPU)
• Fix several bugs which could lead to lost writes in setups without immediate_commit:
  • Client library treated writes as completed before actually completing them, thus missing them in a subsequent fsync
  • Client library didn't repeat writes on the new PG primary when it changed
  • OSDs didn't drop peer connections with dirty writes when stopping PG
• Fix Block Pseudo-FS initialization leading to ENOENTs some time after start
• Fix vitastor-cli merge-based commands (merge/flatten/rm snapshot) slowing down and finally failing when using CAS optimistic locks
• Fix pool create/modify --block_size validation
• Fix TTL comparison for determining failed lease/keepalive requests in OSD
• Add support for size suffixes in pool-create --block_size and --immediate_commit values
