API proposal for functest
1. Propose a basic framework for API 2. And these functions have been realized: 1) Show environment 2) Prepare Environment 3) Show credentials 4) List all testcases 5) Show a testcase 6) List all tiers 7) Show a tier 8) List all testcases within given tier JIRA: FUNCTEST-843 Change-Id: Ib961446708077b56465eda0052f6d38806b62594 Signed-off-by: Linda Wang <wangwulin@huawei.com>
