This change allows Watch users to retrieve the cancel reason when a
watch is canceled by the server. Additionally WatchResponses with
closeErr set now have Canceled set true which is in line with the
documentation for the Canceled field.
Now returns errors from checkPermissionForWatch() via the CancelReason
field. This allows clients to understand why the watch was canceled.
Additionally, this change protects a watch from starting and that
otherwise might hang indefinitely.
Both "client-transport-security" and "peer-transport-security"
is mapped to Go struct embed.securityConfig.
Field for client certificate authentication is tagged as
"client-cert-auth", but it is misspelled in "peer-transport-security"
section.

Useful for automating membership change operations,
no need to run "endpoint status" or "member list"
command to get member IDs.
Also, useful for "etcd_network" metrics with "To/From" labels.

The benchmark as a sub command of put when provided will fetch hashkv and checks
the time taken to get it.
Fixed # 8910
Provider a way to etcd user to check how long it takes to get
hashkv in user enviornment. The command ouput will provide time taken
to get hashkv along with db file size.
etcd server
To improve debuggability of etcd v3. Added a grpc interceptor to log
info on incoming requests to etcd server. The log output includes
remote client info, request content (with value field redacted), request
handling latency, response size, etc. Uses zap logger if available,
otherwise uses capnslog.
Also did some clean up on the chaining of grpc interceptors on server
side.
We allow multiple in-flight append messages, but prior to this change
the only way we'd ever send them is if there is a steady stream of new
proposals. Catching up a follower that is far behind would be
unnecessarily slow (this is exacerbated by a quirk of CockroachDB's
use of raft which limits our ability to catch up via snapshot in some
cases).
See cockroachdb/cockroach#27983
The MaxSizePerMsg setting is now used to limit the size of
Ready.CommittedEntries. This prevents out-of-memory errors if the raft
log has become very large and commits all at once.
