[slurm-users] Slurm missing non primary group memberships

[Douglas Jacobsen]

We've had issues getting sssd to work reliably on compute nodes (at least
at scale), the reason is not fully understood, but basically if the
connection times out with sssd it'll black list the server for 60s, which
then causes those kinds of issues.

Setting LaunchParameters=send_gids will sidestep this issue by doing the
lookups exclusively on the controller node, where more frequent connections
can prevent time decay disconnections and reduce the likelihood of cache
misses.
