Added `version` string to MasterInfo.
Jira: MESOS-2957
Adds an optional version string to the `MasterInfo` protobuf,
to simplify handling versioning in HTTP API calls.
The version string is taken from <mesos/version.hpp> which is the
same used when starting up Master (master/main.cpp).
I've added a simple test on the back of the `MasterDetector` test,
as this was the place where we would expect the `MasterInfo` to
have been fully populated by real production code (as opposed to
other places, where it is actually handled by mocks).

> Currently, the {{MasterInfo}} PB only supports an {{ip}} field as an
> {{int32}}.
> Beyond making it harder (and opaque; open to subtle bugs) for languages other
> than C/C++ to decode into an IPv4 octets, this does not allow Mesos to
> support IPv6 Master nodes.
> We should consider ways to upgrade it in ways that permit us to support both
> IPv4 / IPv6 nodes, and, possibly, in a way that makes it easy for languages
> such as Java/Python that already have PB support, so could easily deserialize
> this information.
> See also MESOS-2709 for more info.
