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
scylla_rsyslog_setup adds a configuration file to rsyslog to forward the
trances to a remote server.
It will override any existing file, so it is safe to run it multiple
times.
It takes an ip, or ip and port from the users for that configuration, if
no port is provided, the default port of Scylla-Monitoring promtail is
used.
