common/LogEntry: drop support of LogSummary v2 encoding scheme

LogSummary's v3 encoding scheme was introduced in
648aaf271cb02c647f046288656c11f15a7799b2, which was in turn included
by Ceph v13.1.0 and all newer releases. since LogSummary is persistented
by monitor, and it is trimmed regularly by monitor, there is no need
to read a LogSummary encoded by 2 releases older monitor.

in this change, the support of LogSummary v2 encoding scheme is dropped.
