The API would expose now the rate_moving_average and
rate_moving_average_and_histogram.
The old end points remains for the transition period, but marked as
depricated.

We do not save the cache, so the get for save priod in second should
return 0, to indicate never like it is done in origin.

Until we'll support key and counter cache, it is reasonable to return 0
for their statistic and sizes.

The API contains stub API methods, this adds a call to unimplemented
method in each of the stubed method that is not implemented.
The return remains the same to help the compiler deduce the return type
of the lambda function.
After this patch a call to an unimplemented API function will return
500.

This adds the implementation for get_row_hits, get_row_requests,
get_row_hit_rate, row_enries, row_size and row_capacity
The implementation is based on the column-family map reduce

This adds a stub implementation for the cache service metrics for key,
row and counters.
A call to the API would return the correct type but with a stub value.
After this patch the following url will be available:
/cache_service/metrics/key/capacity
/cache_service/metrics/key/hits
/cache_service/metrics/key/requests
/cache_service/metrics/key/hit_rate
/cache_service/metrics/key/size

This adds a stub implementation for the cache_service. It also register
the API doc.
The cache_service doc will be available at:
http://localhost:10000/api-doc/cache_service/
The stub implementation returns the correct value type with stubbed
values.
After this patch the following path will be available:
/cache_service/row_cache_save_period
/cache_service/key_cache_save_period
/cache_service/counter_cache_save_period
/cache_service/row_cache_keys_to_save
