A placeholder for snapshotting code that will be moved into it
from the storage_service.
Also -- pass it through the API for future use.

Now with the seastar httpd routes unset() at hands we
can shut down individual API endpoints. Do this for
snapshot calls, this will make snapshot controller stop
safe.

The goal is to make the relevant endpoints work on standalone
thrift controller instead of the storage_service's one, so
prepare this controller (dummy for now) and pass it all the
way down the API code.

Currntly API endpoints to start and stop cql_server and thrift
are registered right after the storage service is started, but
much earlier than those services are. In between these two
points a lot of other stuff gets initialized. This opens a small
window during which cql_server and thrift can be started by
hand too early.
The most obvious problem is -- the storage_service::join_cluster()
may not yet be called, the auth service is thus not started, but
starting cql/thrift needs auth.
Another problem is those endpoints are not unregistered on stop,
thus creating another way to start cql/thrif at wrong time.
Also the endpoints registration change helps further patching.

The set_config registers lambdas that need db.local(), so
these routes must be registered after database is started.

In storage_service's snapshot code there are checks for
_operation_mode being _not_ JOINING to proceed. The intention
is apparently to allow for snapshots only after the cluster
join. However, here's how the start-up code looks like
- _operation_mode = STARTING in storage_service::constructor
- snapshot API registered in api::set_server_storage_service
- _operation_mode = JOINING in storage_service::join_token_ring
So in between steps 2 and 3 snapshots can be taken.
Although there's a quick and simple fix for that (check for the
_operation_mode to be not STARTING either) I think it's better
to register the snapshot API later instead. This will help
greatly to de-bload the storage_service, in particular -- to
incapsulate the _operation_mode properly.
Note, though the check for _operation_mode is made only for
taking snapshot, I move all snapshot ops registration to the
later phase.

There's a lonely get_load_map() call on storage_service that
needs only load broadcaster, always runs on shard 0 and that's it.
Next patch will move this whole stuff into its own helper no-shard
container and this is preparation for this.

Many headers don't really need to include database.hh, the include can
be replaced by forward declarations and/or including the actually needed
headers directly. Some headers don't need this include at all.
Each header was verified to be compilable on its own after the change,
by including it into an empty `.cc` file and compiling it. `.cc` files
that used to get `database.hh` through headers that no longer include it
were changed to include it themselves.

Currently, we register snitch API in set_server_gossip_settle() which
waits until a node has joined the cluster. This makes 'nodetool status'
not properly show the status of a joining node. Fix the issue by
registering snitch API earlier.
Fixes#1269.

The API needs to be available at an early stage of the initialization,
on the other hand not all the specific APIs are available at that time.
This patch breaks the API initialization into stages, in each stage
additional commands will be available.
While setting that the api header files was broken into api_init.hh that
is relevent to the main and to api.hh which holds the different
api helper functions.
Fixes#754
