update the hugepages algorithm as the following steps.
1. calculate the total hugepages of service vm using the formula.
"total memory - the memory consumed by pre-launched VMs - 3G
-1G(memory need by service vm supporting virtio gpu)
-300M*num(number of virtio gpu instance)"
2. calculate hugepage 2M/1G based post-launched vm memory setting.
3. correct the 2M/1G hugepages with the total hugepages in step 1.
"correct_mb, correct_gb= math.modf(total hugepages - the memory
consumed by Post_launched vm)
hugepages_1gb = hugepages_1gb + correct_gb
hugepages_2mb = hugepages_2mb + math.ceil(correct_mb*1024/2)"
