This patch adds context support for Senlin profile. The
following changes were made:
- Adding Senlin profile context;
- Revising 'create_and_delete_profile_cluster' scenario
to make it benchmark cluster creating/deleting only;
- Revising rally-senlin test job and example jobs accordingly;
- Minor fix SenlinMixin cleanup resource to make id
query work correctly;
- Removing admin requirement from profile util functions
since profile creating/deleting doesn't need admin role.
