Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
The manager is needed to get messaging service and database from.
Actually, the database can be pushed though arguments in all the
places, so effectively session only needs the messaging. However,
the stream-task's need the manager badly and there's no other
place to get it from other than the session.

It is 1:1 mapping between session_info and stream_session. Putting
session_info inside stream_session, we can get rid of the
stream_coordinator::host_streaming_data class.
In scylla, in each stream_coordinator, there will be only one
stream_session for each remote peer. Drop the code supporting multiple
stream_sessions in host_streaming_data.
We now have
shared_ptr<stream_session> _stream_session
instead of
std::map<int, shared_ptr<stream_session>> _stream_sessions
- int connections_per_host
Scylla does not create connections per stream_session, instead it uses
rpc, thus connections_per_host is not relevant to scylla.
- bool keep_ss_table_level
- int repaired_at
Scylla does not stream sstable files. They are not relevant to scylla.
messaging_service will use private ip address automatically to connect a
peer node if possible. There is no need for the upper level like
streaming to worry about it. Drop it simplifies things a bit.
I tried our lw_shared_ptr, the compiler complained endless usage of
incomplete type stream_session. I can not include stream_session.hh
everywhere due to circular dependency.
For now, I'm using std::shared_ptr which works fine.
