    cli: Create missing logbuf_pool
    
    Since logbuf_pool was not created via glusterfs_ctx_defaults_init(),
    the following error was present in cli logs repeateadly for each
    and every execution of a gluster command.
    
    E [mem-pool.c:417:mem_get0] (-->/usr/local/lib/libglusterfs.so.0(+0x7e262)
    [0x7fdbc0b1f262] -->/usr/local/lib/libglusterfs.so.0(_gf_msg+0x804)
    [0x7fdbc0ac7844] -->/usr/local/lib/libglusterfs.so.0(mem_get0+0x78)
    [0x7fdbc0af5b48] ) 0-mem-pool: invalid argument [Invalid argument]
    
    This change creates ctx->logbuf_pool via glusterfs_ctx_defaults_init()
    in cli.c so that the above error is no longer logged in cli logs.
