Heat context code refactor

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

At test_case.yaml context segment add "type" to indicate the
context type, see samples/ping-heat-context.yaml for an example.
And the default context type is Heat, so the existing yaml file
do not need to change.

JIRA: YARDSTICK-168
