adapt raft repl dev (#132)

this PR using server_side instead of solo when initialize homestore to adpat raft repl dev. what is more: 1 since raft repl dev does not support recovery, the PR disable recovery related test cases. 2 since we need three instances when testing real 3-replica raft cases and that needs extra works, this PR just using raft group with only one replica to run all the test cases. we can it back to 3 replicas after we implement real 3-replica test framework
