Willy Tarreau f673923629 REGTESTS: extend the default I/O timeouts and make them overridable
With the CI occasionally slowing down, we're starting to see again some
spurious failures despite the long 1-second timeouts. This reports false
positives that are disturbing and doesn't provide as much value as this
could. However at this delay it already becomes a pain for developers
to wait for the tests to complete.

This commit adds support for the new environment variable
HAPROXY_TEST_TIMEOUT that will allow anyone to modify the connect,
client and server timeouts. It was set to 5 seconds by default, which
should be plenty for quite some time in the CI. All relevant values
that were 200ms or above were replaced by this one. A few larger
values were left as they are special. One test for the set-timeout
action that used to rely on a fixed 1-sec value was extended to a
fixed 5-sec, as the timeout is normally not reached, but it needs
to be known to compare the old and new values.

feature ignore_unknown_macro
# This test checks HTTP request buffering feature.
# We run one server s1 which can serve only one client (no -repeat argument here).
# c1 client uses a malformed request which is not transferred to s1 server
# thanks to "http-buffer-request". If this was the case, c2 client
# could not connect to s1 server and this would lead to make this test fail.
