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
Which configures seastar to act more appropriate to a tool app. I.e.
don't act as if it owns the place, taking over all system resources.
These tools are often run on a developer machine, or even next to a
running scylla instance, we want them to be the least intrusive
possible.
Also use the new tool mode in the existing tools.
