Port health in detailed page fails to load for many ports

[cjones051073]

See e.g.

https://ports.macports.org/port/python313/details/

The port health section on the right fails to load, it just gets stuck in a "Loading Port Health" spinning wheel of doom indefinitely,

Does not seem to happen for all ports, a few for whatever reason seem to load OK, e.g.

https://ports.macports.org/port/bzip2/details/

This was happening because for some ports the number of files is too large. In these cases, the queryset returned is too big for memcached to cache.

For now I have increased the size of item memcached can cache, but ideally we should reduce the size of the returned queryset. So let's keep this issue open.
