Add 3 arguments to run.simple.bash: DOLOAD DOQUERY SEED
* when DOLOAD="yes" then the database is loaded
* when DOQUERY="yes" then the query test is run
* SEED is the seed for the RNG to avoid or force use of the same random number sequences

Change jmongosysbenchexecute.java to take new arguments:
* auto_commit replaces read_only and when true begin/commit is not called. This can make TokuMX faster.
* seed passes the seed for the RNG
* inserts is the number of inserts to do

With this change inserts and updates are done unless SYSBENCH_INSERTS, SYSBENCH_NON_INDEX_UPDATES
and SYSBENCH_INDEX_UPDATES are set to 0
