Use the new seastar option to instruct seastar to not initialize and use the seastar allocator, relying on the standard allocator instead. Configure LSA with the standard allocator based segment store backend: * scylla-types reserves 1MB for LSA -- in theory nothing here should use LSA, but just in case... * scylla-sstable reserves 100MB for LSA, to avoid excessive trashing in the sstable index caches. With this, tools now should allocate memory on demand, without reserving a large chunk of (or all of) the available memory, as regular seastar apps do.
