Is your feature request related to a problem? Please describe.

By default Agones batches allocations for better throughput by 500ms at a time. In some scenarios, that amount of wait time is overkill. But what happens in allocation and the tradeoffs for changing this value is not documented anywhere, so it's hard to judge.

Describe the solution you'd like

The following documentation added:

• How Agones Allocation batching works
• How to configure it (already exists in Helm config, but good to reiterate)
• The tradeoffs there (may impact CPU and potentially throughput).

I was thinking here:
https://agones.dev/site/docs/reference/gameserverallocation/

Maybe with an update to the formatting of how the cache performs.

Describe alternatives you've considered

Leave the documentation alone - but the issue has come up a few times in offline discussions, so its worth documenting.
