lsst-dev01:/ssd/lsstsw/stack deprecated

Following RFC-527, I have disabled automatic updates to the “shared stack” at /ssd/lsstsw/stack on lsst-dev01.

As of now, I’ve not removed the existing builds, which remain available for use. However, you should regard them as “at risk”: they’re consuming a goodly portion of the space on that disk, and I will remove them without further warning when we run out of room. Please take steps now to migrate to the stack at /software/lsstsw/stack instead.

The documentation at https://developer.lsst.io/services/lsst-dev.html#load-the-lsst-environment will be updated to reflect this change (and the fact that we’ve dropped Python 2 support) shortly.

We ran out of room. They are gone. :wave:
