TS-3729 cache_promote: defer TSHttpTxnServerRespNoStoreSet() to a global
continuation, saves a possible race condition
> cache_promote: Can crash / assert under conditions where origin is very slow

>
> If the response from origin is very slow (> 60s), until ATS gets the headers,
> there's a window where cache_promote can assert and crash, when remap.config
> is reloaded on a live system. This is a similar problem to other places where
> we ended up having to ref-count the continuation and remap configuration.
> Since we defer the cache control until "read-response-header" due to TS-3426,
> this is an unfortunate (and temporary) problem. At the point where this hook
> needs to execute, we don't need access to the remap data or continuation, so
> my solution / proposal is that we just use a global continuation that is
> unrelated to the remap configs, and schedule it when this deferred cache
> control is needed. Later, we can then remove it completely.
