[Feature] L2 inbound rate limiting

[andygolay]

This feature:

(NICE TO HAVE)
Mvmt Labs can set a (total token) volume rate limit on the L2 contract that rejects DVN's completion of transfers on L2. The rate limit on L2 is equal or higher than the rate limit on L1. The rate limit is such that the L2MOVE pool does not get depleted. (this requires diligent human observation of remaining pool balance).

is one that has been discussed on Slack but not formally decided upon.

I tend to think that monitoring the L2 MOVE and topping it up as needed should suffice to ensure that the L2 MOVE pool does not get depleted.
