It should be moved to i_partitioner.hh, but to do that range<> has to
be first moved out of query-request.hh to break cyclic dependency.
I didn't want to cause conflicts with in-flight patches to range<>.
range::is_wrap_around() and range::contains() rely on total ordering
on values to work properly. Current ring_position_comparator was only
imposing a weak ordering (token positions equal to all key positions
with that token).
range::before() and range::after() can't work for weak ordering. If
the bound is exclusive, we don't know if user-provided token position
is inside or outside.
Also, is_wrap_around() can't properly detect wrap around in all
cases. Consider this case:
(1) ]A; B]
(2) [A; B]
For A = (tok1) and B = (tok1, key1), (1) is a wrap around and (2) is
not. Without total ordering between A and B, range::is_wrap_around() can't
tell that.
I think the simplest soution is to define a total ordering on
ring_position by making token positions positioned either before or
after all keys with that token.
Support to compaction strategy options was recently added.
Previously, we were using default values in compaction strategy for
options, but now we can use the options defined in the schema.
Currently, we only support size-tiered strategy, so let's start
with it.

Translate more is_member() checks like in commit 67f4b55 ("gms/gossiper:
Fix is_gossip_only_member() logic").
This hopefully cures #36.

Because we will do from and to sstring operations on it, it needs
a default value. The lack of it is causing our tests to fail.
This should have been included in the original patch but I have somehow
missed it. Sorry.

All sharded services "should" define a stop method. Calling them is also
a good practice. For this one specifically, though, we will not call stop.
We miss a good way to add a Deleter to a shared_ptr class, and that would
be the only reliable way to tie into its lifetime.

Blindly calling it at exit is wrong, but it is less wrong than not calling
it at all, and makes it now equally as wrong as any of the other services.

The destructor depends on a lot of things (like the thrift lib classes), that
are not visible from the .hh. It works fine so far because nobody is trying to
destroy it explicitly either. But soon I will.

"This is my current proposal for Compact Storage tables - plus
the needed infrastructure.
Getting rid of the CellName abstraction allows us to simplify
things by quite a lot: now all we need is to mark whether or
not a table is composite, and provide functions to play the
role of the comparator when dealing with the strings."
The migration_manager and migration_task logging is currently not
visible in the logs. Fix that by de-thread-localizing both loggers.
