MINOR: checks: Support log-format string to set the URI for HTTP send rules For http-check send rules, it is now possible to use a log-format string to set the request URI. the keyword "uri-lf" should be used instead of "uri". If the string eval fails, we fall back on the default uri "/".

BUG/MAJOR: tcpcheck: Allocate input and output buffers from the buffer pool Historically, the input and output buffers of a check are allocated by hand during the startup, with a specific size (not necessarily the same than other buffers). But since the recent refactoring of the checks to rely exclusively on the tcp-checks and to use the underlying mux layer, this part is totally buggy. Indeed, because these buffers are now passed to a mux, they maybe be swapped if a zero-copy is possible. In fact, for now it is only possible in h2_rcv_buf(). Thus the bug concretely only exists if a h2 health-check is performed. But, it is a latent bug for other muxes. Another problem is the size of these buffers. because it may differ for the other buffer size, it might be source of bugs. Finally, for configurations with hundreds of thousands of servers, having 2 buffers per check always allocated may be an issue. To fix the bug, we now allocate these buffers when required using the buffer pool. Thus not-running checks don't waste memory and muxes may swap them if possible. The only drawback is the check buffers have now always the same size than buffers used by the streams. This deprecates indirectly the "tune.chksize" global option. In addition, the http-check regtest have been update to perform some h2 health-checks. Many thanks to @VigneshSP94 for its help on this bug. This patch should solve the issue #936. It relies on the commit "MINOR: tcpcheck: Don't handle anymore in-progress send rules in tcpcheck_main". Both must be backport as far as 2.2. bla

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.

MINOR: checks: Use ver keyword to specify the HTTP version for http checks 'ver' keyword is already used by sample fetches while 'vsn' is not used anywhere else. So better to use 'ver' too for http-check send rules.
