Usually the consistent_index should be greater than the index of the
latest snapshot with suffix .snap. But for the snapshot coming from the
leader, the consistent_index should be equal to the snapshot index.
Downstream users of etcd experience build issues when using dependencies
which require more recent (incompatible) versions of opentelemetry. This
commit upgrades the dependencies so that downstream users stop
experiencing these issues.
The code now ensures that each of the test is running in its own directory as opposed to shared os.tempdir.

The reason was that the path exceeded 108 chars (that is too much for socket).
In the mitigation we first change chroot (working directory) to the tempDir... such the path is 'local'.
The directory created by `T.TempDir()` and is automatically removed when
the test and all its subtests complete.

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`.
Use the FileLockEx wrapper and the corresponding LOCKFILE_* and error
constants from the golang.org/x/sys/windows package rather than
implementing these in the fileutil package.
Used github.com/stretchr/testify/assert to replace the AssertEqual function definition. Required the use of copyToInterface to copy a string slice to the empty interface slice
