[core] Fix #380 by working around recorder/logger initialization timing.

The HdrHistogramReader makes some problematic assumptions on the roles
played by start time, base time and histogram start/end times. This is
to be revisited in a future release of HdrHistogram (see
https://github.com/HdrHistogram/HdrHistogram/issues/69). In the meantime
this change will make YCSB record as expected by the reader:
a. Set histogram log base time (same as start time)
b. Only create the recorder after the log has been setup

In order to get the tests to pass again, reverted MongoDbClient to use update with upsert instead of insert when batch size is 1.

Added journal=true back into MongoDB connection string.  For now, the connection string will contain both "j" and "journal", until such time as the MongoDB Java driver supports "journal".

Simplified insert CRUD code to always use insertMany even when batchSize == 1,
 as there is no performance penalty for this in the driver.

Changed visibility of static field from protected to private in final OptionsSupport class for MongoDB.
