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
In order to improve observability, add a username field to the the
system_traces.sessions table. The system table should be change
while upgrading by running the fix_system_distributed_tables.py
script. Until the table is updated, the old behaviour is preserved.
Fixes#6737.
If a port value passed as a string this makes the cluster.connect() to
fail with Python3.4.
Let's fix this by explicitly declaring a 'port' argument as 'int'.
Fixes#4527

This patch makes the tracing framework follow the general idea of Google's
Dapper paper: traces generated in a context of the same query are forming
a single-rooted acyclic tree where in a ScyllaDB case vertexes are spans running
on each involved replica Node and edges are RPCs sent from one Node to another.
- Each vertex in the tree above has an ID - "span ID".
- In order to be able to build the tree from the sessions traces we need
to know the parent "span ID" - the ID of a span that sent an RPC that created
the current span.
- Each span of a tracing session is given a 64-bit random span ID.
- The root span has a span_id::illegal_id value.
This patch adds:
- The described above parent span ID and a span ID to the one_session_records
object.
- The current span ID is passed in the trace_info struct to the remote replica.
- Add parent_id and span_id columns to system_traces.events table for the parent
ID and span ID.

This script validates schemas of distributed system keyspaces:
system_traces and system_auth.
It tries to add the missing columns and checks that the existing columns
have expected types.
In case of any problem the corresponding info message is printed and non-zero exit
status is returned.
Extra columns are ignored.
The validation function may also be called from another Python program.
It returns True in case of success and False otherwise.
