nova/flavors: Add new HANA flavors with NUMA traits

HANA flavors require a fitting `CUSTOM_NUMASIZE_*` trait, that can be
applied to hosts that provide the appropriate NUMA node size. HANA
flavors also reserve all of their memory, by requesting the
(SAP-custom) resource "CUSTOM_MEMORY_RESERVABLE_MB".

hana_c384_m5835 is commented out because it is dependent on an updated
VSphere for supporting more than 256 vCPUs.

Note that any HANA flavor above 1TB of RAM still requires the
CUSTOM_BIGVM resource. In the future, VMs with HANA flavors should live
on dedicated hardware which would obviate the whole BigVM-/special-
spawning mechanic. Remove the CUSTOM_BIGVM resource requirement then.
