Report key events to dotnet diagnostics infrastructure.

[sanych-sun]

Consider raising events into dotnet diagnostics infrastructure to cover key points in the library life-cycle. Have to investigate and implement counters (for number of delivered or published messages for example), report key events (for example, connection open, connection broken, etc) as well as some way to report a time spend by different components of the library (for example, time of serialization).
