> Smooth decrease of the write speed in WAL when approaching the exhaustion of current segments in the working directory.
> Now archiver segment switch involves file copying and may be bottleneck of speed of grid operation.
> Now if out of work segments occurs, grid put speed drop down to 0 ops/sec ocurred.
> This isssue was fixed under IGNITE-7017 with providing new 'NoArchvier' mode, but in case archiver based WAL is already used by end-user, it is required to have opportunity to smooth decrease speed instead of drop to 0.
