Fixed regression

Bump to 1.6.2

Added PrefetchCount setting to RabbitMqConnectionConfiguration to give users full control over setting. Set a default value of '1' - merely for this to be a non-breaking change from previous releases. This, however, is not a sensible settng in production as it disables parallel execution of jobs from the same queue.

Upgraded Hangfire dependencies to 1.6.x for all to be on same minor version. Updated nuspec dependencies accordingly.

Fix for xUnit test runner consistently failing with CannotUnloadAppDomainException:

Bumped to 1.6.1 to be above current NuGet version

docker-compose file added to run RabbitMQ instance in Docker neede for tests
