Sysconfig charm does not allow specifying default_hugepagesz=1G

Imported from Launchpad using lp2gh.

(by jfguedez) Configuring "hugepages=64" and "hugepagesz=1G" in the charm does not lead to 64 1G hugepages:

grep Huge /proc/meminfo

AnonHugePages: 4096 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB Hugetlb: 67108864 kB

Had to add to add default_hugepagesz=1GB outside of the charm to enable the functionality:

grep Huge /proc/meminfo

AnonHugePages: 4096 kB ShmemHugePages: 0 kB FileHugePages: 0 kB HugePages_Total: 64 HugePages_Free: 64 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 1048576 kB Hugetlb: 67108864 kB
