MINOR: cache: Create res.cache_hit and res.cache_name sample fetches Res.cache_hit sample fetch returns a boolean which is true when the HTTP response was built out of a cache. The cache's name is returned by the res.cache_name sample_fetch. This resolves GitHub issue #900.

REGTESTS: disable inter-thread idle connection sharing on sensitive tests Some regtests involve multiple requests from multiple clients, which can be dispatched as multiple requests to a server. It turns out that the idle connection sharing works so well that very quickly few connections are used, and regularly some of the remaining idle server connections time out at the moment they were going to be reused, causing those random "HTTP header incomplete" traces in the logs that make them fail often. In the end this is only an artefact of the test environment. And indeed, some tests like normalize-uri which perform a lot of reuse fail very often, about 20-30% of the times in the CI, and 100% of the time in local when running 1000 tests in a row. Others like ubase64, sample_fetches or vary_* fail less often but still a lot in tests. This patch addresses this by adding "tune.idle-pool.shared off" to all tests which have at least twice as many requests as clients. It proves very effective as no single error happens on normalize-uri anymore after 10000 tests. Also 100 full runs of all tests yield no error anymore. One test is tricky, http_abortonclose, it used to fail ~10 times per 1000 runs and with this workaround still fails once every 1000 runs. But the test is complex and there's a warning in it mentioning a possible issue when run in parallel due to a port reuse.
