Supplement block_log.artifacts implementation
- It should allow self verification (i.e. hash computed from few first and last entries shall be stored in header). Then during each load given hash should be checked again to verify sanity
- It should store (in the header) a checksum of few start and last block_log entries (blocks) to verify matching between above 2 files
- At loading it should print above checksums, what also would allow to easify verify matching files across servers
- Add dedicated checks (at hived side) which will force regeneration when artifact file was dirty closed, or does not match to any of checksums mentioned above
- Improve generation algorithm, to speedup this process on slower drives. Related to #196 (closed)
- Implement real support for interrupt and resume of generation process.
