Difference in load configuration for watch delay tests show how huge the
impact is. Even with random write scheduler grpc under http
server can only handle 500 KB with 2 seconds delay. On the other hand,
separate grpc server easily hits 10, 100 or even 1000 MB within 100 miliseconds.
Priority write scheduler that was used in most previous releases
is far worse than random one.
Tests configured to only 5 MB to avoid flakes and taking too long to fill
etcd.

Added optional TLS min/max protocol version and command line switches to set
versions for the etcd server.
If max version is not explicitly set by the user, let Go select the max
version which is currently TLSv1.3. Previously max version was set to TLSv1.2.

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

The default max stream is 250 in http2. When there are more then
250 streams, the client side may be blocked until some previous
streams are released. So we need to support configuring a larger
`MaxConcurrentStreams`.

There is no update on the original PR (see below) for more then 2
weeks. So Benjamin(@ahrtr) continues to work on the PR. The first
step is to rebase the PR, because there are lots of conflicts with
the main branch.
The change to go.mod and go.sum reverted, because they are not needed.
The e2e test cases are also reverted, because they are not correct.

The ClientConfig is a fully declarive configuration, so it makes more
sense to rename it to ConfigSpec. It can also mitigate the confusion
between Config and ClientConfig.
Currently the discovery url is just one endpoint. But actually it
should be the same as the etcdctl, which means that it should be
a list of endpoints. When one endpoint is down, the clientv3 can
fail over to the next endpoint automatically.
To avoid inconsistant behavior during cluster upgrade we are feature
gating persistance behind cluster version. This should ensure that
all cluster members are upgraded to v3.6 before changing behavior.
To allow backporting this fix to v3.5 we are also introducing flag
--experimental-enable-lease-checkpoint-persist that will allow for
smooth upgrade in v3.5 clusters with this feature enabled.
The io/ioutil package has been deprecated as of Go 1.16, see
https://golang.org/doc/go1.16#ioutil. This commit replaces the existing
io/ioutil functions with their new definitions in io and os packages.

Json encoding is the default zap encoding value and can not be changeable.
This PR enables configuring zap encoding to console via new flag `log-format`.
When a unary request takes more than predefined duration, this request
is defined as "expensive" and a warning is printed. The expensive request
duration is hard-coded to 300 ms. It can be not enough for example
for transactions with a lot of operations. The warnings just blow up
the log files and reduce throughput.
This fix allows user to configure the "expensive" request duration.

Flags `--experimental-enable-v2v3` and '-enable-v2' will raise a warning in 3.5,
in 3.6 they are schedule for decomissioning, such that v2store can stop be written in 3.7.
