mgw: Avoid hardcoding in test the amount of endpoints configured in osmo-mgw 

Some tests require to match what's configured in osmo-mgw.
Let's make it possible to change it through a module parameter.
This will be needed for a follow-up patch to test >256 concurrent osmux
conns, which will require increasing the number of configured endpoints
above that value.
