Automated tests for huge pages

Scenarios to automate
Case1:
1. Enable support of huge pages
2. Set size of pages for 1 compute
3. Deploy cluster with 1 compute
4. Create flavor with specific key
5. Check that flavor with specific key is presented
6. Launch VM with created flavor
7. Run Network check
8. Run OSTF tests

Case2:
1. Enable support of huge pages
2. Set size of pages for 2 compute
3. Deploy cluster with 2 compute
4. Create flavors with specific key
5. Check that flavors with specific key are presented
6. Launch VM with created flavor
7. Run Network check
8. Run OSTF tests

Case3.
1. Don't enable support of huge pages
3. Deploy cluster with 1 compute
4. Create flavor with specific key
5. Check that flavor with specific key isn't presented
6. Run Network check
7. Run OSTF tests

Case4.
1. Enable support of huge pages for first compute
2. Set size of pages for first compute
