Change the token_metadata type to token_metadata2 in
the signatures of CDC-related methods in
storage_service and cdc/generation. Use
get_new_strong to get a pointer to the new host_id-based
token_metadata from the inet_address-based one,
living in the shared_token_metadata.
The starting point of the patch is in
storage_service::handle_global_request. We change the
tmptr type to token_metadata2 and propagate the change
down the call chains. This includes token-related methods
of the boot_strapper class.
