We should call Wait for grpc-proxy process stop before start. Otherwise,
the tcp port won't be released.

1. Fixed the test failures which are caused by recent test framework rafactoring;
2. renamed the file to promote_experimental_flag_test.go.

--warning-unary-request-duration is a duplicate of --experimental-warning-unary-request-duration
experimental-warning-unary-request-duration will be removed in v3.7.

ExpectProcess and ExpectFunc now take the exit code of the process into
account, not just the matching of the tty output.
This also refactors the many tests that were previously succeeding on
matching an output from a failing cmd execution.

When e2e test cases specify the DataDirPath and there are more than
one member in the cluster, we need to create a subdirectory for each
member. Otherwise all members share the same directory and accordingly
lead to conflict.

ClusterContext is used by "e2e" or "integration" to extend the
ClusterConfig. The common test cases shouldn't care about what
data is encoded or included; instead "e2e" or "integration"
framework should decode or parse it separately.

In the TestDowngradeUpgradeCluster case, the brand-new cluster is using
simple-config-changer, which means that entries has been committed
before leader election and these entries will be applied when etcdserver
starts to receive apply-requests. The simple-config-changer will mark
the `confState` dirty and the storage backend precommit hook will update
the `confState`.
For the new cluster, the storage version is nil at the beginning. And
it will be v3.5 if the `confState` record has been committed. And it
will be >v3.5 if the `storageVersion` record has been committed.
When the new cluster is ready, the leader will set init cluster version
with v3.6.x. And then it will trigger the `monitorStorageVersion` to
update the `storageVersion` to v3.6.x. If the `confState` record has
been updated before cluster version update, we will get storageVersion
record.
If the storage backend doesn't commit in time, the
`monitorStorageVersion` won't update the version because of `cannot
detect storage schema version: missing confstate information`.
And then we file the downgrade request before next round of
`monitorStorageVersion`(per 4 second), the cluster version will be
v3.5.0 which is equal to the `UnsafeDetectSchemaVersion`'s result.
And we won't see that `The server is ready to downgrade`.
It is easy to reproduce the issue if you use cpuset or taskset to limit
in two cpus.
So, we should wait for the new cluster's storage ready before downgrade
request.

It doesn't make sense to always pass a AuthConfig parameter for
test cases which do not enable auth at all. So refactoring the
Client interface method so that it accepts a `ClientOption`
variadic parameter.
