Add code to actually stream data from other nodes during bootstrap.
I tested with the following:
1) stat a node 1
2) insert data into node 1
3) start node 2
I can see from the logger that data is streamed correctly from node 1
to node 2.
unordered_set is used everywhere for tokens. This makes it is easier to
construct a boot_strapper object in storage_service::bootstrap where
unordered_set is used for tokens.
Aside from being the obviously correct thing to do, not having this will force us
to manually adjust num_tokens when running our sstables into Cassandra.

It needs to access the non-existent "DatabaseDescriptor". Do as we have been doing,
and just pass the database object instead.

We do not care about the order of the tokens.
Also, in token_metadata, we use unordered_set for tokens as well, e.g.
update_normal_tokens. Unify the usage.
