James Parker 071426c223 Test resize with mem_page_size in flavor
These tests are meant to address issue [1]. It adds three new testcases:

 * test_hugepage_resize_keyword_large_to_small
 * test_hugepage_resize_explicit_pagesize_to_small
 * test_hugepage_resize_explicit_size_to_size

All three tests follow the same basic procedure, spawn a guest with a
flavor using hw:mem_page_size:<size_a>, resize the guest to a flavor
with a different size hw:mem_page_size:<size_b>, and then resize the
guest back to the original flavor. Throughout the tests XML checks are
conducted to ensure the page size is accurate for the present flavor.

Instead of trying to dynamically determine the hugepage sizes configured
on the computes, a new config parameter was added to define what
hugepage sizes are available on the host. To avoid dynamic ram
calculation sizes for the guest based on available hugepages, a guest
ram parameter was also added so users may define the size to use when
spawning guests.

We also need a new job that has multiple hugepage sizes configured. We
cannot use our existing whitebox-devstack-multinode job because that
one runs tests that dynamically turn on file backed memory, which is
incompatible with hugepages. This commit adds tasks into job setup
that allows for the setup of hugepages.

In our devstack plugin.sh, we set track_instance_changes to True
(devstack defaults it to False) to make sure the scheduler has the
latest information about available huge pages, and avoid a race
whereing instances failed to schedule because our lone 1G page
still appeared used by an instance that had actually beed fully
deleted.
