[Beowulf] Bright Cluster Manager

[Douglas Eadline]

Here is where I see it going

1. Computer nodes with a base minimal generic Linux OS
   (with PR_SET_NO_NEW_PRIVS in kernel, added in 3.5)

2. A Scheduler (that supports containers)

3. Containers (Singularity mostly)

All "provisioning" is moved to the container. There will be edge cases of
course, but applications will be pulled down from
a container repos and "just run"
