[noha] Bring in FDIO (VPP+DPDK) scenario
- cmp, gtw: bump RAM allocation to accomodate hugepages/VPP; for now we overcommit, gtw01 resources can probably be lowered; - submodule: add salt-formula-neutron so we can locally patch it; - repo: * FD.IO repos for VPP packages; * networking-vpp PPA for python-networking-vpp Neutron driver; - use vpp-router for L3, disable neutron-l3-agent; - baremetal_init: apply repo config before network (otherwise UCA repo is missing when trying to install DPDK on baremetal nodes); - arm64: iommu.passthrough=1 is required on ThunderX for VPP on newer kernels; Design quirks: - vpp service runs as 'neutron' user, which does not exist at the time VPP is installed and initially started, hence the need to restart it before starting the vpp-agent service; - gtw01 node has DPDK, yet to configure it via IDF we use the compute-specific OVS-targeted parameters like `compute_ovs_dpdk_socket_mem`, which is a bit misleading; - vpp-agent requires ml2_conf.ini on ALL compute AND network nodes to parse per-node physnet-to-real interface names; - vpp process is bound to core '1' (not parameterized via IDF); Change-Id: I659f7dbebcab7b154e7b1fb829cd7159b4372ec8 Signed-off-by: Alexandru Avadanii <Alexandru.Avadanii@enea.com> (cherry picked from commit 455b46a6be4bca145c047ed6957727c119285796)
