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 ease future extensions to the information being sent
by the service level configuration change API, we pack the additional
parameters (other the the service level options) to the interface in a
structure. This will allow an easy expansion in the future if more
parameters needs to be sent to the observer.i
