http: maintain curl sessions
Allow curl sessions to be kept alive (ie. not ended with
curl_easy_cleanup()) even after the request is completed, the number of
which is determined by the configuration setting http.minSessions.
Add a count for curl sessions, and update it, across slots, when
starting and ending curl sessions.
