Review request for mesos, Benno Evers, Gastón Kleiman, and Greg Mann.


Significant change from previous revision(s):

* The master **and** agent's `HttpConnection` structs have been pulled into a common header
due to their similarities.  This common header is renamed and tweaked, so it appears much
more explicitly named in the code.
* The Heartbeater helper has arguments more directly copied from the master now.  These arguments
were previously changed to remove the templating.  Having a templatized class may allow us
to modify the heartbeat message before sending it, i.e. adding a timestamp.
* The Heartbeater class now has a wrapper class to handle the actor lifecycle.

Summary (updated)

Refactored master and agent streaming connections.

Bugs: MESOS-7564

Repository: mesos

Description (updated)

This moves the very similar `HttpConnection` classes inside the
master and agent into a common header.  The refactored
`StreamingHttpConnection<Event>` is more explicitly named to avoid
potentially clashing with the libprocess HTTP helpers.

This also moves the master's heartbeater helper into a new header
and transforms it into an RAII libprocess actor wrapper.  The 
heartbeater depends on this `StreamingHttpConnection` and is currently
used by the master for heartbeating the operator event stream
and HTTP framework connection.  A later patch will use this heartbeater
for agent->executor heartbeats.

The original plan was to use the same helper for the executor too, but of the Master, Framework,
and Agent heartbeats, only the executor lacks a streaming connection.
