Support for adjusting batch-size in ProcessUpdateIndexQueueCommand

[jremmurd]

With this PR it gets possible to adjust the batch size using the existing command option.

Example: bin/console ecommerce:indexservice:process-update-queue --timeout=5 --processes=3 --batch-size=50

From the docs:

The batch size is determined by getBatchSize() and defaults to the segment
size. The segment size is the number of items a worker (child) process
consumes before it dies. This means that, by default, a child process will
process all its items, persist them in a batch and then die. If you want
to improve the performance of your command, try to tweak getSegmentSize()
first. Optionally, you can tweak getBatchSize() to process multiple batches
in each child process.

@jremmurd Could you please rebase this PR to the 2.x branch? There won’t be a 1.4 release. Thanks!

no need for rebase when chaging base-branch to upstream :-)
