Gluster users - Mar 2019 - Release 6: Tagged and ready for packaging

Hi,

RC1 testing is complete and blockers have been addressed. The release is
now tagged for a final round of packaging and package testing before
release.

Thanks for testing out the RC builds and reporting issues that needed to
be addressed.

As packaging and final package testing is finishing up, we would be
writing the upgrade guide for the release as well, before announcing the
release for general consumption.
