[07/15] config: add job.pack-files.batchSize option

Commit Message

From: Derrick Stolee <[e-mail]>

The previous change allowed a user to specify a --batch-size=<size>
option to 'git run-job pack-files'. However, when we eventually
launch these jobs on a schedule, we want users to be able to change
this value through config options.

The new "job.pack-files.batchSize" option will override the default
dynamic batch-size calculation, but will be overridden by the
--batch-size=<size> argument.

This is the first config option of the type
"job.<job-name>.<option>" but is not the last.
