Golang uses a `sync.Once` when determining the proxy to use. This means
that it's not possible to test the proxy configuration in unit tests,
because the proxy configuration will be "fixated" the first time Golang
detects the proxy configuration.
This patch changes TestNewAPIClientFromFlagsWithHttpProxyEnv to an e2e
test so that we can verify the CLI picks up the proxy configuration.

Some tests were using domain names that were intended to be "fake", but are
actually registered domain names (such as mycorp.com).
Even though we were not actually making connections to these domains, it's
better to use domains that are designated for testing/examples in RFC2606:

Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.
With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;
Unsupported signal: <nil>. Discarding.
To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;
```patch

This patch checks if the channel is closed, and removes the warning (to prevent warnings if new
signals are added that are not in our known list of signals)
We should also consider updating `notfiyAllSignals()`, which currently forwards
_all_ signals (`signal.Notify(sigc)` without passing a list of signals), and
instead pass it "all signals _minus_ the signals we don't want forwarded":
