Do not store cached_dir_t for consensus in RAM if not a dircache.
There are three reasons we use a cached_dir_t to hold a consensus:
1. to serve that consensus to a client
2. to apply a consensus diff to an existing consensus
3. to send the consensus to a controller.
But case 1 is dircache-only. Case 2 and case 3 both fall back to
networkstatus_read_cached_consensus(). So there's no reason for us
to store this as a client. Avoiding this saves about 23% of our RAM
usage, according to our experiments last month.
This is, semantically, a partial revert of e5c608e535ef9a4c4fe951a2.
Fixes bug 27247; bugfix on 0.3.0.1-alpha.
