More changes as part of the dualstack design:
- Change resolver and LB policy APIs to support multiple addresses per
endpoint. Specifically, replace `ServerAddress` with
`EndpointAddresses`, which encodes more than one address. Per-address
channel args are retained at the same level, so they are now
per-endpoint. For now, `EndpointAddress` provides a single-address ctor
and a single-address accessor for backward compatibility, so
`ServerAdress` is an alias for `EndpointAddresses`; eventually, this
alias and the single-address methods will be removed.
- Add an `EndpointAddressSet` class, which represents an unordered set
of addresses to be used as a map key. This will be used in a number of
LB policies that need to store per-endpoint state.
- Change the LB policy API's `ChannelControlHelper::CreateSubchannel()`
method to take the address and per-endpoint channel args as separate
parameters, so that we don't need to construct a legacy `ServerAddress`
object as we create a new subchannel for each address in the endpoint.
- Change pick_first to flatten the address list.
- Change ring_hash to use `EndpointAddressSet` as the key for its
endpoint map, and to use the first address of the endpoint as the hash
key.
- Change WRR to use `EndpointAddressSet` as the key for its endpoint
weight map.
Note that support for multiple addresses per endpoint is guarded in RR
by the existing `round_robin_delegate_to_pick_fist` experiment and in
WRR by the existing `wrr_delegate_to_pick_first` experiment.
This PR does *not* include support for multiple addresses per endpoint
for the outlier_detection or xds_override_host LB policies; those will
come in subsequent PRs.
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.
This PR is a small code change with a lot of new test data.
[In OpenSSL, there are two flags that configure CRL checks. Coping
relevant
section:](https://www.openssl.org/docs/man1.0.2/man3/X509_VERIFY_PARAM_get_depth.html)
> - X509_V_FLAG_CRL_CHECK enables CRL checking for the certificate chain
leaf certificate. An error occurs if a suitable CRL cannot be found.
> - X509_V_FLAG_CRL_CHECK_ALL enables CRL checking for the entire
certificate chain.
We currently only set `X509_V_FLAG_CRL_CHECK`, so we will only ever
check if the leaf certificate is revoked. We should check the whole
chain. I am open to making this a user configuration if we want to do it
that way, but we certainly need to be able to check the whole chain.
So, this PR contains the small code change in
`ssl_transport_security.cc` to use the `X509_V_FLAG_CRL_CHECK_ALL` flag.
Then the rest of the changes are in tests. I've added all the necessary
files to have a chain built that looks as follows
`Root CA -> Revoked Intermediate CA -> Leaf Certificate`, and added a
test for this case as well.
You can verify that on master this new test will fail (i.e. the
handshake will succeed even though the intermediate CA is revoked) by
checking out this branch, running `git checkout master --
./src/core/tsi/ssl_transport_security.cc`, then running the test.
I also slightly reorganized test/core/tsi/test_creds/ so that the CRLs
are in their own directory, which is the way our API intends to accept
CRLs.
We have many tests that create 100 threads or more, and mounting evidence that
this is harmful to our CI environment.
When the original code for many of these tests was written we ran our tests
under run_tests, which had explicit handling for tracking the number of threads
each test needed and making sure that we weren't over subscribing the test
runner. Bazel has no such facility (and the facility in run_tests has since
been removed) and so we need to adjust.
This PR adjusts down a single test and is part of a series so that we can
review and roll back easily if required.

Based on a handful of https://abseil.io/tips, it's generally advised to
only fully-qualify namespaces when in a `using` statement, or when it's
otherwise required for compilation. In all other cases, the general
recommendation is to not fully-qualify.
This change fixes most `grpc.*` namespace uses. There are potential
challenges in trying to make blanket changes to non-gRPC namespace uses,
such as `::testing`, since there is also a `grpc::testing` namespace.
