Heat context code refactor part 2

Heat context code refactor to cater for the evolution of the
Yardstick framework.

Refactor runner_cfg host/target info handle, as specified at
https://etherpad.opnfv.org/p/yardstick_framework
step 4. Get general Context info (use Context.get).

Before this refactor host and target vm must have the same user name
and ssh key, that is not general enough for later extension.

test_case.yaml do NOT need to change.
