instead of v3.0.0-000101010000000-00000000000,
that might be misleading as we don't develop etcd v3.0.0 any longer.
This version is a virtual version and is not supposed to be tagged
within the repository. We should tag real versions like: 3.5.0-alpha.0.
Please notice that go.etcd.io/etcd/client/v2 will be versioned as `v2.305.0-pre`.
The reason is that client v2 must have v2 version. I propose a
convention to envode the major version as 100x in minor version to make
the association to the underlying repository clear, staying within v2
version family.
The change was generated using:
```
DRY_RUN=false TARGET_VERSION="v3.5.0-pre" ./scripts/release_mod.sh update_versions
```
We make v2 client code a module go.etcd.io/etcd/client/v2.
Pretty mechanical change that can be summarized as:
mkdir client/v2
cd client/v2 && git mod init go.etcd.io/etcd/client/v2
git mv client/*.go client/v2/
find -name '*.go' | xargs sed -i --follow-symlinks 's|/v3/client["]|/client/v2\"|g'
+ fixing changelog, bom, go.mod etc.
This brings consistency between proto-generation code and actual versions of libraries being used in runtime:
github.com/gogo/protobuf v1.2.1,v1.0.0 -> v1.3.1
github.com/golang/protobuf v1.3.2 -> v1.3.5
github.com/grpc-ecosystem/grpc-gateway v1.9.5,v1.4.1,v1.15.2 -> v1.14.6
google.golang.org/grpc v1.26.0 -> v1.29.1
Moved as far as possible, without bumping on grpc 1.30.0 "naming" decomissioning.
Please also notice that gogo/protobuf is likely to reach EOL: https://github.com/gogo/protobuf/issues/691
Direct syscalls using syscall.Syscall(SYS_*, ...) should no longer be
used on darwin, see [1]. Instead, use the fcntl libSystem wrappers
provided by the golang.org/x/sys/unix package which implement the same
functionality.

The fix is needed to mitigate consequences of
https://github.com/golang/go/issues/29458 "golang breaking change" that
causes following test failures on etcd end:
--- FAIL: TestCtlV2Set (0.00s)
ctl_v2_test.go:552: could not start etcd process cluster (fork/exec ../../bin/etcd: Setctty set but Ctty not valid in child)
--- FAIL: TestCtlV2SetQuorum (0.00s)
ctl_v2_test.go:552: could not start etcd process cluster (fork/exec ../../bin/etcd: Setctty set but Ctty not valid in child)
--- FAIL: TestCtlV2SetClientTLS (0.00s)

This change makes the etcd package compatible with the existing Go
ecosystem for module versioning.
Used this tool to update package imports:

The quorum package contains logic to reason about committed indexes as
well as vote outcomes for both majority and joint quorums. The package
is oblivious to the existence of learner replicas.
The plan is to hook this up to etcd/raft in subsequent commits.
To remove the dependency on ghodss/yaml. Replaced this dependency with sigs.k8s.io/yaml.
This wil help to remove the ghodss/yaml dependency from main kubernetes repository.
