Extend the parent domain object with custom allocation callbacks that
can be used by user-applications to override the provider allocation.
This can be used for example to add NUMA aware allocation.
The new allocator receives context information about the parent domain,
as well as the requested size and alignment of the buffer. It also
receives a vendor-specific resource type code to allow customizing it
for specific resources.
The allocator then allocates the memory or returns an
IBV_ALLOCATOR_USE_DEFAULT value to request that the provider driver use
its own allocation method.

It is unclear to me how and maybe it is not possible for this API. but I
would expect any changes in public API be accompanied by relevant tests.
The current pyverbs infrastructure has some lack in this area to enable
adding a simple test over.
The infrastructure team is working to find a solution and may push it
once be ready later on.
