1. ec2_servers has been commited to rally and our ec2_server object
now conflicts with rally`s. in this patchset our object has been renamed.
2. rally now doesn't save context between runs. it passes original context
to each run. before this feature we stored something in context and
didn't count first run. moved to using global var of ec2 plugin.
rally was changed here - https://review.openstack.org/#/c/203911/9
3. added route tables preparation for floating ip associating.
4. Scenarios was refactored in rally
