Theta Programming Environment Upgraded on July 27

Theta OS was upgraded from SLES12/CNL6 configuration to SLES15/CNL7 on July 22. On July 27, the Programming Environment was updated to the latest version 6.0.7 that Cray offers. This is necessary for full compatibility with the previously completed OS upgrade. This will require some user codes to be rebuilt and/or relinked; packages previously built with Spack will no longer work and will need to be rebuilt.
