KUDU-3371 [fs] make LogBlockManager as a base class

This patch makes LogBlockManager as a base class, and adds
FileMetaLogBlockManager inherit from it.
FileMetaLogBlockManageris the log-backed block manager which
manage the sequential written file to store containers' metadata,
it is how we do as before.

Most of member functions are left in base class LogBlockManager
to avoid too large updating on existing code, I'm planning to do
that in next patches.
