Following C* API there are two APIs for getting the load from
storage_service:
/storage_service/metrics/load
/storage_service/load
This patch adds the implementation for
/storage_service/metrics/load
The alternative, is to drop on of the API and modify the JMX
implementation to use the same API.

Commit d41cd48a made the is_joined() method a future<bool> because
only cpu 0 knows its real value. This makes this function inconvenient
to use. So this patch reverts commit d41cd48a, and instead sets this
flag's value on all shards, so each shard can read its value locally
(and immediately).

- Change an exception type thrown by a tracing::tracing::set_trace_probability()
to make it different from the one thrown by an std::stod() when it fails to
parse a given string.
- Catch the std::out_of_range exception thrown by a tracing::tracing::set_trace_probability() and
wrap the exception string into the httpd::bad_param_exception() object.
- Throw a httpd::bad_param_exception() with a
"Bad format in a probability value: <a user given probability string value>"
message if std::invalid_argument is caught.

There are places in which we need to use the column family object many
times, with deferring points in between. Because the column family may
have been destroyed in the deferring point, we need to go and find it
again.
If we use lw_shared_ptr, however, we'll be able to at least guarantee
that the object will be alive. Some users will still need to check, if
they want to guarantee that the column family wasn't removed. But others
that only need to make sure we don't access an invalid object will be
able to avoid the cost of re-finding it just fine.

- kill -9 node2
- wait for node2 to be in DOWN state

'nodetool enable/disablebackup' callback was modifying only the
existing keyspaces and column families configurations.
However new keyspaces/column families were using
the original 'incremental_backups' configuration value which could
be different from the value configured by 'nodetool enable/disablebackup'
user command.
This patch updates the database::_enable_incremental_backups per-shard
value in addition to updating the existing keyspaces and column families
configurations.

To implement nodetool's "--start-token"/"--end-token" feature, we need
to be able to repair only *part* of the ranges held by this node.
Our REST API already had a "ranges" option where the tool can list the
specific ranges to repair, but using this interface in the JMX
implementation is inconvenient, because it requires the *Java* code
to be able to intersect the given start/end token range with the actual
ranges held by the repaired node.
A more reasonable approach, which this patch uses, is to add new
"startToken"/"endToken" options to the repair's REST API. What these
options do is is to find the node's token ranges as usual, and only
then *intersect* them with the user-specified token range. The JMX
implementation becomes much simpler (in a separate patch for scylla-jmx)
and the real work is done in the C++ code, where it belongs, not in
Java code.
With the additional scylla-jmx patch to use the new REST API options
provided here, this fixes#917.

cleanup is handled asynchronously. To solve that, a mechanism is
added here to wait for termination of a cleanup. This mechanism is
about using promise to notificate waiter of cleanup completion.

"This series solve an issue with the load broadcaster that reports negative
values due to an integer wrap around. While fixing this issue an additional
change was made so that the load_map would return doubles and not formatted
string. This is a better API, safer and better documented."
The repair API use to have an undocumented parameter list similiar to
origin.
This patch changes the way repair is getting its parameters.
Instead of a one undocumented string it now lists all the different
optional parameters in the swagger file and accept them explicitely.

In origin the storage_serivce report the load map as a formatted string.
As an API a better option is to report the load map as double and let
the JMX proxy do the formatting.

This patch chanages the API to support describe ring instead of describe
ring jmx that will be implemented in the jmx server.
The API will return a list of objects instead of string.
An additional api was added as the equivelent to the jmx call with an
