Release 3.0.1

Important fixes:

- Disable RWF_ATOMIC by default because Linux incorrectly requires all atomic
  writes to be power-of-2-sized and length-aligned. Details: [use_atomic_flag](https://vitastor.io/en/docs/config/osd.html#use_atomic_flag)
- Fix cross-pool snapshots not working at all - always reading old data after taking the snapshot
- Fix level_placement (broken in 2.2.0)
- Fix CAS write return values in the client library (broken in 2.4.4), also breaking unaligned writes in VitastorFS
- Fix VitastorFS possibly losing some of intersecting parallel unaligned writes
- Prevent possible reads of the old data during unfinished intent writes in the new store
- Tests added for all of above problems to prevent future regressions

Other fixes:

- Allow to specify OSD tags and weights during prepare
- Only clear the first block instead of whole OSD metadata and journal areas during vitastor-disk
  prepare - OSD anyway clears them on the first run
- Fix vitastor-cli dd non-seekable detection and error status
- Do not stop OSD on zero-copy tcp short send errors - these aren't a bug, but just caused
  by TCP client disconnections
- Fix modify-osd not working after deleting the OSD configuration key from etcd
- Fix regular antietcd websocket disconnections in OSD due to lack of WS_PONG responses to WS_PING
- Reduce the number of allocated RDMA memory regions
- Allow routed RoCE
