136f89dfc5 e2e: use error wrapping with %w
The recently introduced failure handling in ExpectNoError depends on error
wrapping: if an error prefix gets added with `fmt.Errorf("foo: %v", err)`, then
ExpectNoError cannot detect that the root cause is an assertion failure and
then will add another useless "unexpected error" prefix and will not dump the
additional failure information (currently the backtrace inside the E2E
framework).

Instead of manually deciding on a case-by-case basis where %w is needed, all
error wrapping was updated automatically with

    sed -i "s/fmt.Errorf\(.*\): '*\(%s\|%v\)'*\",\(.* err)\)/fmt.Errorf\1: %w\",\3/" $(git grep -l 'fmt.Errorf' test/e2e*)

This may be unnecessary in some cases, but it's not wrong.

1793132198 e2e storage: avoid usage of stdin for file creation
It turned out to be unreliable (see
https://github.com/kubernetes/kubernetes/issues/112834).  Encoding the data
inside the command as input for base64 is a workaround that is fine for small
amounts of data. It becomes less efficient and/or unusable for large amounts.

0bd9a1a29a e2e storage: close all pending streams when proxy listener gets closed
After updating gRPC in node-driver-registrar from v1.40.0 to v1.47.0 the
behavior of gRPC change in a way such that it no longer detected the
single-sided closing of the stream as a loss of connection. This caused gRPC in
the e2e.test to get stuck, possibly in a Read or Write for the HTTP stream
because those have neither a context nor a timeout.

Changing the connection handling so that all active connections are tracking in
the listener and closing them when the listener gets closed fixed this problem.

d43308e64c e2e storage: simpler port forwarding
Instead of trying to use the client-go portforward package as-is it is
simpler to copy some code from it and then use the http stream
directly. That way we don't need to go through a local listening
socket and error handling and logging becomes simpler.

3adcf11b45 e2e storage: use embedded mock CSI driver
This replaces embedding of JavaScript code into the mock driver that
runs inside the cluster with Go callbacks which run inside the
e2e.test suite itself. In contrast to the JavaScript hooks, they have
direct access to all parameters and can fabricate arbitrary responses,
not just error codes.

Because the callbacks run in the same process as the test itself, it
is possible to set up two-way communication via shared variables or
channels. This opens the door for writing better tests. Some of the
existing tests that poll mock driver output could be simplified, but
that can be addressed later.

For now, only tests using hooks use embedding. How gRPC calls are
retrieved is abstracted behind the CSIMockTestDriver interface, so
tests don't need to be modified when switching between embedding
and remote mock driver.
