5d7c1db3a9 Introduce grpc-1.30+ compatible client/v3/naming API.
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.

351bdb33c5 Split intengration/clientv3 tests into multiple packages
They used to take >10min with coverage, so were causing interrupted
Travis runs.

Know thay fit in 100-150s (together), thanks also to parallel
execution.

f2a912a4e6 test: change channel operations to avoid potential goroutine leaks
In these unit tests, goroutines may leak if certain branches are chosen. This commit edits channel operations and buffer sizes, so no matter what branch is chosen, the test will end correctly. This commit doesn't change the semantics of unit tests.

45b007b8b4 contrib,clientv3: Move contrib/recipies to clientv3/experimental/recipies/...
Recipies is set of patterns / primitives implementation on top of clientv3.
It's used by integration tests. It shouldn't be considered "server" code.

45e4306508 client: Move client to client/v2 as a module.
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.

30811a06aa etcdctl, clientv3/snapshot: snapshot (Restore,Status) code out of client
"snapshot" Restore/Status code was the only remaining dependency of client on 'server'
code. The code is solelly used by etcdctl. Long-term the snapshot code
should be migrated to 'etcdadm' style of tool such that we can
distinguish tool solelly depending on networking API vs. tools that
operation on etcd files directly.

We left snapshot.Save() code in clientv3.snapshot package, such that
clients can benefits from automated download&safe to file snapshot
functionality over the wire.

73b92fe688 tests: Make examples (for not client) to be both: documentation and integration-runnable
This CL tries to connect 2 objectives:
  - Examples should be close (the same package) to the original code,
    such that they can participate in documentation.
  - Examples should be runnable - such that they are not getting out of
    sync with underlying API/implementation.

In case of etcd-client, the examples are assuming running 'integration'
style, i.e. thay do connect to fully functional etcd-server.
That would lead to a cyclic dependencies between modules:
  - server depends on client (as client need to be lightweight)
  - client (for test purposes) depend on server.
Go modules does not allow to distingush testing dependency from
prod-code dependency.

Thus to meet the objective:
  - The examples are getting executed within testing/integration packages against real etcd
  - The examples are symlinked to 'unit' tests, such that they included in documentation.
  - Long-term the unit examples should get rewritten to use 'mocks' instead of real integration tests.
