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.
Instead, distribute those inclusions to .cc files that require them. This
reduces rebuilds when config.hh changes, and makes it easier to locate files
that need config disaggregation.
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.
