MINOR: http: start to compute the transaction's cacheability from the request

There has always been something odd with the way the cache-control flags
are checked. Since it was made for checking for the risk of leaking cookies
only, all the processing was done in the response. Because of this it is not
possible to reuse the transaction flags correctly for use with the cache.

This patch starts to change this by moving the method check in the request
so that we know very early whether the transaction is expected to be cacheable
and that this status evolves along with checked headers. For now it's not
enough to use from the cache yet but at least it makes the flag more
consistent along the transaction processing.
