Subject: [PATCH] Reduce maximum number of service instances for sandbox and
 alpha

We want to lower the maximum number of service instances as much as
possible without affecting service reliability so that we can make
stronger statements about what the maximum cost of running a typical
Nomulus environment might be. This first step likely won't affect the
frontend and tools modules in practice because they aren't typically
running even this many instances, but it will clamp down on the
number of backend instances (which should be fine; it just means the
mapreduces will take longer).

Alpha is tuned down the same as sandbox for consistency reasons.
This also standardizes on the B4 size (which has 512 MiB RAM) for
all instances. Most instances were already using this, and the
deviations from it were seemingly at random. Crucially, backend,
which is likely most sensitive to this because it uses the mapreduce
library, is already on the smaller memory size.
