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
Some state accessors called get_local_gossiper(); this is removed
and replaced with a parameter. Some callers (redis, alternators)
now have the gossiper passed as a parameter during initialization
so they can use the adjusted API.
Pass down gossiper from main, converting it to a shard-local instance
in calls to register_api() (which is the point that broadcasts the
endpoint registration across shards).
This helps remove gossiper as a global variable.
The upstream of origin adds the version to the application_state in the
get_endpoints in the failure detector.
In our implementation we return an object to the jmx proxy and the proxy
do the string formatting.
This patch adds the version to the return object which is both useful as
an API and will allow the jmx proxy to add it to its output when we move
forward with the jmx version.

In origin, get_all_endpoint_states perform all the information
formatting and returns a string.
This is not a good API approach, this patch replaces the implementation
so the API will return an array of values and the JMX will do the
formatting.
This is a better API and would make it simpler in the future to stay in
sync with origin output.
This patch is part of #508

/failure_detector/count/endpoint/down
/failure_detector/phi
POST:/failure_detector/phi
/failure_detector/simple_states
/failure_detector/endpoints/states
