feat(v1.1): Implement new /health endpoint for v1.1

The new /health endpoint of v1.1 is different from the /health
of v1.0. In v1.1 /health endpoint we will return a set of KPI
(Key Performance Indicator) of the target Marconi server. The
API response will be like below:

Improve benchmarking tool

This commit adds several enhancements to benchmarking tool: server_url
and path to messages now can be configured in config file.  Default
output of program has been changed: now it prints values in json so they
can be parsed more easily. Previous human readable representation is
accessible via --verbose flag.

The `total_requests` metric now shows all performed requests (either
failed or successful) and new metric - `successful_requests` - was
introduced to store count of successful requests.
