This PR is expected to fix the flakes of
`//test/core/tsi:ssl_transport_security_test` when built under UBSAN.
Why is this needed? There are several tests in
`ssl_transport_security_test.cc` that involve doing many expensive
operations and PR #33638 recently added one more (namely, repeatedly
signing with an ECDSA key). The slow tests are already altered for MSAN
and TSAN, and now we need to do the same for UBSAN.
Scenarios for language `node` specify the server language as `node`
(instead of leaving it blank), so a flag must be added to
`--allow_server_language=node`.
Scenarios for language `node_purejs` differ in name and in scenario
settings, but otherwise run on identical clients and servers. This
change treats `node_purejs` as `node` for the purpose of generating load
test configurations.
Those tests are failing on CIs which do not have twisted installed. Skip
them for now and will fix the docker images next.

This PR implements a c-ares based DNS resolver for EventEngine with the
reference from the original
[grpc_ares_wrapper.h](../blob/master/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.h).
The PosixEventEngine DNSResolver is implemented on top of that. Tests
which use the client channel resolver API
([resolver.h](../blob/master/src/core/lib/resolver/resolver.h#L54)) are
ported, namely the
[resolver_component_test.cc](../blob/master/test/cpp/naming/resolver_component_test.cc)
and the
[cancel_ares_query_test.cc](../blob/master/test/cpp/naming/cancel_ares_query_test.cc).
The WindowsEventEngine DNSResolver will use the same EventEngine's
grpc_ares_wrapper and will be worked on next.
The
[resolve_address_test.cc](https://github.com/grpc/grpc/blob/master/test/core/iomgr/resolve_address_test.cc)
which uses the iomgr
[DNSResolver](../blob/master/src/core/lib/iomgr/resolve_address.h#L44)
API has been ported to EventEngine's dns_test.cc. That leaves only 2
tests which use iomgr's API, notably the
[dns_resolver_cooldown_test.cc](../blob/master/test/core/client_channel/resolvers/dns_resolver_cooldown_test.cc)
and the
[goaway_server_test.cc](../blob/master/test/core/end2end/goaway_server_test.cc)
which probably need to be restructured to use EventEngine DNSResolver
(for one thing they override the original grpc_ares_wrapper's free
functions). I will try to tackle these in the next step.

https://github.com/grpc/grpc/pull/33699 incorrectly changed the legacy
builds to not just use the test driver from the master, but also to
build from it. This PR fixes the issue, and also updates the python job
to work use the driver from master.
follow up from #33590

We are seeing `g++: fatal error: Killed signal terminated program
cc1plus` on PHP distribtest builds. In case it's an OOM, let's try
reducing the build parallelism to see if it helps.
Promises code can prevent these bad requests from even reaching the
application, which is beneficial but this test needs a minor update to
handle it.

This test has been disabled for a long time now due to flakiness, but
it's now causing problems with the import. And stress tests don't
provide positive ROI anyway, so let's just get rid of it.

There is a bug in the SSL stack that was only partially fixed in #29176:
if more than 17kb is written to the BIO buffer, then everything over
17kb will be discarded, and the SSL handshake will fail with a bad
record mac error or hang if not enough bytes have arrived yet.
It's relatively uncommon to hit this bug, because the TLS handshake
messages need to be much larger than normal for you to have a chance of
hitting this bug. However, there was a separate bug in the SSL stack
(recently fixed in #33558) that causes the ServerHello produced by a
gRPC-C++ TLS server to grow linearly in size with the size of the trust
bundle; these 2 bugs combined to cause a large number of TLS handshake
failures for gRPC-C++ clients talking to gRPC-C++ servers when the
server had a large trust bundle.
This PR fixes the bug by ensuring that all bytes are successfully
written to the BIO buffer. An initial quick fix for this bug was planned
in #33611, but abandoned because we were worried about temporarily
doubling the memory footprint of all SSL channels.
The complexity in this PR is mostly in the test: it is fairly tricky to
force gRPC-C++'s SSL stack to generate a sufficiently large ServerHello
to trigger this bug.
Going forward `[[nodiscard]]` is the portable way to spell this;
requires yanking a bunch of usage from after the param list to before.
We should further refine the GRPC_MUST_USE_RESULT macro to make it work
uniformly for any compilers that it doesn't today (most likely by making
it expand to nothing).

PanCakes to the rescue!
We noticed that our 'sanity' test was going to fail, but we think we can
fix that automatically, so we put together this PR to do just that!

URI should be resolved to unix abstract only if the first byte is NULL
but the path length is > 1 (i.e there is more than one byte in the
path). Otherwise treat is as unix URI.
Moreover, when the AsyncConnectionAcceptor is destroyed, if it was
managing a unix domain socket, then the socket should be unlinked to
ensure we dont leave the underlying file hanging around forever.
This (or something like it) is necessary for the automated protobuf
upgrade script, to ensure we don't commit a redundant third_party tree
to the repo. Here is an example of the protobuf upgrade without this
fix: https://github.com/grpc/grpc/pull/33625
One alternative could be adding the filepaths to `.gitignore`.

Note that the plugin is still under `grpc::internal` namespace and not
under `experimental` intentionally.
