Add rocky-container-stackhpc

Provides 9-stackhpc containerfile

Uses cloud-init with NM support from c9s and explicitly
sets network renderer and activator to network-manager.

In addition to that install 'Minimal Install' dnf group
to get the core packages installed - currently lacks
microcode_ctl amongst others (so we don't update microcode
on CPUs to mitigate vulnerabilities).
