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.

The etcdctl and etcdutl built with `-tags cov` mode will show go-test result
after each execution, like
```
...
PASS
coverage: 0.0% of statements in ./...
```
Since the PASS is not real command, the `source completion` command will
fail with command-not-found error. And there is no easy way to disable
the (*testing.M).Run's output. Therefore, this patch uses build tag !cov
to disable cases when enable coverage.

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.

This fix avoids the assumption of knowing the current version of the
binary. We can query the binary with the version flag to get the actual
version of the given binary we upgrade and downgrade to. The
respectively reported versions should match what is returned by the
version endpoint.

Afer moving `ClusterVersion` and related constants into e2e packages,
some e2e test cases are broken, so we need to update them to use the
correct definitions.

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.

submitConcurrentWatch use sleep 3s to wait for all the watch connections
ready. When the number of connections increases, like 1000, the 3s is not
enough and the test case becomes flaky.
In this commit, spawn curl process and check the ouput line with
`created":true}}` to make sure that the connection has been initialized
and ready to receive the events. It is reliable to test the following
range request.

Due to a duplicate call of clientConfigFromCmd, the move-leader command
would fail with "conflicting environment variable is shadowed by corresponding command-line flag".
Also in scenarios where no command-line flag was supplied.
