The schwag was introduced to generate swagger with authorization support
[1][1] in 2017. And in 2018, the grpc-gateway supports to render
security fields by protoc-gen-swagger [2][2]. After several years, I
think it's good to use upstream protoc supports.
NOTE:
The json's key in `rpc.swagger.json` has been reordered so that it seems
that there's a lot of changes. How to verify it:
```bash
$ # use jq -S to sort the key
$ latest_commit="https://raw.githubusercontent.com/etcd-io/etcd/228f493c7697ce3e9d3a1d831bcffad175846c75/Documentation/dev-guide/apispec/swagger/rpc.swagger.json"
$ curl -s "${latest_commit}" | jq -S . > /tmp/old.json
$ cat Documentation/dev-guide/apispec/swagger/rpc.swagger.json | jq -S . > /tmp/new.json
$ diff --color -u /tmp/old.json /tmp/new.json
```

However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n URL, or have them precompiled into a binary to avoid any\n lookup. Therefore, binary compatibility needs to be preserved\n on changes to types.

When performing the downgrade operation, users can confirm whether each member
is ready to be downgraded using the field 'storageVersion'. If it's equal to the
'target version' in the downgrade command, then it's ready to be downgraded;
otherwise, the etcd member is still in progress of processing the db file.
This is not yet implementation, just API and tests to be filled
with implementation in next CLs,
tracked by: https://github.com/etcd-io/etcd/issues/12652
We propose here 3 packages:
- clientv3/naming/endpoints ->
That is abstraction layer over etcd that allows to write, read &
watch Endpoints information. It's independent from GRPC API. It hides
the storage details.
- clientv3/naming/endpoints/internal ->
That contains the grpc's compatible Update class to preserve the
internal JSON mashalling format.
- clientv3/naming/resolver ->
That implements the GRPC resolver API, such that etcd can be
used for connection.Dial in grpc.
Please see the grpc_naming.md document changes & grpcproxy/cluster.go
new integration, to see how the new abstractions work.
This changes have started at etcdctl under auth.go, and make changes to stub out everything down into the internal raft. Made changes to the .proto files and regenerated them so that the local version would build successfully.
This commit adds a feature for creating a user without password. The
purpose of the feature is reducing attack surface by configuring bad
passwords (CN based auth will be allowed for the user).
The feature can be used with `--no-password` of `etcdctl user add`
command.
Fix https://github.com/coreos/etcd/issues/9590
- Added isLearner flag to MemberAddRequest in Cluster API.
- Added isLearner field to StatusResponse in Maintenance API.
- Added MemberPromote rpc to Cluster API.
Currently, when we access the URL https://www.grpc.io, it is redirected to https://www.grpc.io automatically.
So this commit aims to replace **HTTP** to **HTTPs** for security.
