If user configures a wrong storeEngine, log an log with more details. Only ClassNotFoundException is handled since misconfiguration will easily trigger it.

> When user misconfigures 'hbase.hstore.engine.class', region server complains "Class not found" and gives up. In this case, we need to load the DefaultStoreEngine to avoid that. Sanity check needs to be done to prevent user from misconfiguration as well.
