hastd: Add full lifecycle testHEADmain

Add a test case that creates and starts two nodes, has one assume the
primary role and the other the secondary role, writes to the device,
verifies that the data is synced to both nodes, then switches the roles,
and finally shuts both nodes down and compares their backing stores.
