Let testr be aware of sanity testcase runtimes

times.dbm is a prepopulated anydbm file which testr manages to figure
out how to schedule parallel tests.
With this knowledge, it is seen that parallel sanity tests( 4 runs in
parallel) completes in a little over an hour (~4200 secs)

Also, add a tool to manually add/delete testcase run-times into the db
