gfapi: add mem_pools_init and mem_pools_fini calls
These are both needed because GFAPI clients are a bit unique. They can be long-running, so they can potentially benefit from the memory reclamation that mem_pools_init will enable. On the other hand, they might completely tear down their Gluster environment well before the process exits, so they need mem_pools_fini as well. Our main and auxiliary daemons do need mem_pools_init but don't need to call it themselves because that's handled for them in glusterfsd.c right after they daemonize. They don't need mem_pools_fini, because the only place they could *safely* call it is right before exit and then it won't do them any good. Transient processes (e.g. gf_attach) don't benefit from either because, well, they're transient. They'll be gone before memory reclamation matters.
