[Gluster-Maintainers] Stop sending patches for and merging patches on release-3.7

[Kaushal M]

Hi all,

GlusterFS-3.7.20 is intended to be the final release for release-3.7.
3.7 enters EOL with the expected release of 3.10 in about 2 weeks.

Once 3.10 is released I'll be closing any open bugs on 3.7 and
abandoning any patches on review.

So as the subject says, developers please stop sending changes to
release-3.7, and maintainers please don't merge any more changes onto
release-3.7.
