There is nothing really that fundamentally ties the estimated histogram to
sstables. This patch gets rid of the few incidental ties. They are:
- the namespace name, which is now moved to utils. Users inside sstables/
now need to add a namespace prefix, while the ones outside have to change
it to the right one
- sstables::merge, which has a very non-descriptive name to begin with, is
changed to a more descriptive name that can live inside utils/
- the disk_types.hh include has to be removed - but it had no reason to be
here in the first place.
Todo, is to actually move the file outside sstables/. That is done in a separate
step for clarity.

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.

This patch expose the configuration timeout values of the timers.
The timers will return their values in seconds, the swagger definition
file was modified to reflect the change.

This adds a workaround for the get schema_version, it will return only a
shcema version of the local node, this is a temporary workaround until
describe_schema_versions will be implemented.

This patch add some missing definition for cas read an write, the API
definition is for completness only as we do not support cas yet.
It also change a part of the definition from storage_service to
storage_proxy as it should be.

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 an implementation to the storage_service counters. The
implementation uses the stats object inside the storage_proxy.

This adds a stub implementation for the storage_proxy.
To simplify future implementation, it takes the passed parameter and
return the correct types with fixed values.
