hz-bbw5 - OOM due to docker workload requestion too much resources

hz-bbw5

• RAM: 128 GB
• CPU's : 32, 1 socket, 64 threads

Current docker workload:

amd64-debian-12-asan-ubsan

    - > Jobs = 20

amd64-debian-12-rocksdb

    - > Jobs = 20

amd64-debian-11-msan-clang-16

     -> Jobs = 30

In the worst case scenario, all three builders requesting a build on hz-bbw5 would result in 70/64 CPU parity which is not acceptable given that:

• we run libvirt workers for amd64 on this machine
• we run mariadb replica (crossreference) on this machine

Proposed:

amd64-debian-12-asan-ubsan

    - > Jobs = 10

amd64-debian-12-rocksdb

    - > Jobs = 10

amd64-debian-11-msan-clang-16

     -> Jobs = 20

This will leave some error margin for the other workloads hopefully avoding further OOM.
