Not all the API command are implemented it would be better that the user
would receive an error if it tries to call an unimplmeneted API call.
This adds an unimplemented_exception that would be thrown when an API
call is not implemented.
The unimplemented method, simply throws the exception.

Avi asked not to use an atomic integer to produce ids for repair
operations. The existing code had another bug: It could return some
id immediately, but because our start_repair() hasn't started running
code on cpu 0 yet, the new id was not yet registered and if we were to
call repair_get_status() for this id too quickly, it could fail.
The solution for both issues is that start_repair() should return not
an int, but a future<int>: the integer id is incremented on cpu 0 (so
no atomics are needed), and then returned and the future is fulfilled.
Note that the future returned by start_repair() does not wait for the
repair to be over - just for its index to be registered and be usable
to a call to repair_get_status().

"This series address issues #59 and #23.
It moves the API configuration from the command line argument to the general
config, it also move the api-doc directory to be configurable instead of hard
coded."
Fixes#59Fixes#23
This patch addresses issu #155, it adds a helper function that if a
keyspace does not exists it throw a bad parameter exception.

$ curl -X POST --header "Content-Type: application/json" --header "Accept:
application/json" "http://127.0.0.1:10000/storage_service/gossiping"
btw, the description looks incorrect:
POST /storage_service/gossiping
allows a user to recover a forcibly 'killed' node
This adds the ownwership method implementation to the storage_service
API. After the patch the following url will be supported:
GET /storage_service/ownership/{keyspace}
GET /storage_service/ownership/

This adds the API for get_effective_ownership and
get_ownership in storage_service.
It is based on the StorageServiceMBean definition.

This adds the column family mean row size in the per column family and
the total version. I uses the ratio_helper class to calculate the mean
over all the shrades.
This distinguish between the async repair that starts the repair, that
will now be a POST request and the method that check on the command
progress that will now be a GET command.
After the change each operation would get the parameters that it needs.
The GET will return an enum based on the repair_status.

Adding to API function to return count of sstables in L0 if leveled
compaction strategy is enabled, 0 otherwise. Currently, we don't
support leveled compaction strategy, so function to return count of
sstables in L0 always return zero.

Some of the APIs need to return a ratio.
The ratio_holder struct is a helper class that counts the total and the
sub totat, it implements the json::jsonable virtual class with a
to_json method that return the ratio.
The main usage of the sturct is with a map-reduce method.
