[sheepdog] [PATCH v2 1/9] tests/functional: add test to check wrong node joining with newer epoch

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

This test can be passed after I refined the sheepdog start-up
procedure, but it's still meaningful to have this test for detecting
degradation.
