This CL fixes:
COVERDIR=./coverage PASSES="build_cov" && go test --tags cov -v ./tests/e2e
and is part of the effort to make:
COVERDIR=coverage PASSES="build_cov cov" ./test
fully pass.
The args passed to ./bin/etcd_test and ./bin/etcdctl_test binaries were
mismatched. The protocol of passing the arguments using
environment variables has been replaces with proper passing of flags.
How the measurement of coverage by e2e tests works:
1. COVERDIR=./coverage PASSES="build_cov" are generating
./bin/etcd_test and ./bin/etcdctl_test binaries.
2. These binaries are tests (as coverage can be computed only for
tests) [see ./main_test.go ./etcdctl/main_test.go], but this tests are
running the main logic of the server and uppon termination (or SIGTERM
signal) are writting proper .coverprofile files in the $COVERDIR folder.
The binaries used to take arguments using env variables, but its not
needed any longer. The binaries can consume any command line arguments
that either test (so --test.fooo) or the original binary can consume.
3. The tests/e2e (when compiled with the --tags cov) are starting the
_test binaries instead of the original binaries, such that the coverage
is being collected.
This change makes the etcd package compatible with the existing Go
ecosystem for module versioning.

Since syscall.Errno implements net.Error and all cases
are matched sequentially, it's a mistake to put syscall.Errno
case after net.Error since it will never be executed.
This change swaps syscall.Errno case with net.Error
to give that clause chance to execute.
etcdctl was checking if the user exists before applying mutable calls;
if etcdctl contacts a minority member, the member may not know the user
exists on the cluster yet, causing command failure when it should succeed.
If the user does not exist, it will be picked up once the command goes
through raft.
Fixes#6932
If the WAL is stored in a separate directory then the backup command
would need a --wal-dir option to pick the path to the WAL directory.
The user might also want to store the backup of data and wal separately
for which --backup-wal-dir option is provided.
