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
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.
It is used to force remove a node from gossip membership if something
goes wrong.
Note: run the force_remove_endpoint api at the same time on _all_ the
nodes in the cluster in order to prevent the removed nodes come back.
Becasue nodes without running the force_remove_endpoint api cmd can
gossip around the removed node information to other nodes in 2 *
ring_delay (2 * 30 seconds by default) time.
For instance, in a 3 nodes cluster, node 3 is decommissioned, to remove
node 3 from gossip membership prior the auto removal (3 days by
default), run the api cmd on both node 1 and node 2 at the same time.
$ curl -X POST --header "Accept: application/json"
"http://127.0.0.1:10000/gossiper/force_remove_endpoint/127.0.0.3"
$ curl -X POST --header "Accept: application/json"
"http://127.0.0.2:10000/gossiper/force_remove_endpoint/127.0.0.3"
Then run 'nodetool gossipinfo' on all the nodes to check the removed nodes
are not present.
Fixes#2134Closes#5436
We were not consistent about using '#include "foo.hh"' instead of
'#include <foo.hh>' for scylla's own headers. This patch fixes that
inconsistency and, to enforce it, changes the build to use -iquote
instead of -I to find those headers.

_unreachable_endpoints is replicated to call cores. No need to query on
core 0.
This also fixes a bug in storage_proxy::truncate_blocking
which might access _unreachable_endpoints on non-zero cores.
This patch clean up the gossiper implementation by using the new square
bracket operator for path param and by using the general function
container_to_vec.

This implement the gossipier API. All actions perform on the local
gossiper.
The following functionality is supported:
/gossiper/downtime/{addr}
/gossiper/generation_number/{addr}
/gossiper/assassinate/{addr}
The following are extened API beyond the MBean definition:
/gossiper/endpoint/down
/gossiper/endpoint/live
