[sheepdog] [PATCH] Add test case to test data integrity after changing my address of sheep process

[Ruoyu]

If modifying the "my address" of sheep process parameter without intention, the cluster treates it as a new node so that we know the operation is wrong. However, when trying to revert, we find out the prior created vdi is lost.

new: tests/functional/088 and 088.out: test case and expected output
modified: tests/functional/common.filter: add function of filtering ip address
modified: tests/functional/group: test case name and define
