    Use xz as compression tool for snapshot

    Default compression level will: -3

    Played with it on logs with ~6Gb of data

    Snapshot compressed with:
    - gzip takes: 479m Mb
    - xz 3 level - 272 and takes 4 minutes
    - xz 9 level - 239 and takes ~ 30 min

    It is possible to use pixz utility that will run compressing
    on multiple cores, but i dont think it is wise to depend on it,
    because when master host will be installed on vm - it may take
    very long time to generate snapshot

This feature will be introduced in 6.1, why it is moved to 7.0?

It's a documentation bug, so it was decided it will be added in 7.0 documentation.
