upgrades all necessary containers to htcondor10

• upgrades local condor cluster containers to images based on AlmaLinux8, prep for RHEL8 cluster conversion
• the AL8 images use a different packages system than the old centos7 images - had to rewrite boot-execute.sh for python3.10 install

Any volunteers to dump their local containers and give this a spin?

I purged and rebuilt my containers on this branch and was able to successfully run a null capability so it seems to be working thus far.

Also, woof about that almalinux.

Me too!
