Taking a look we do see some things like this_shard_id() being called, but other than that it doesn't look like it should be problematic. But, it's unclear if there is more lurking there. Changed the test to run things that log using seastar logger on a seastar thread. Signed-off-by: Noah Watkins <noahwatkins@gmail.com>

The tee_wrapper helper was being used to set the ostream pointer for global logger to be an ostream instance that lived only on the stack, and not resetting it to something global like std::cerr after the test finished. This resulted in the following segfault in other tests that ran after the change but didn't make their own change to ostream pointer: ``` #0 0x7f875b0bbc1f in std::__1::basic_ostream<char, std::__1::char_traits<char> >::sentry::sentry(std::__1::basic_ostream<char, std::__1::char_traits<char> >&) (/vectorized/lib/libc++.so.1+0x65c1f) #1 0x5597c3979afc in std::__1::basic_ostream<char, std::__1::char_traits<char> >& std::__1::__put_character_sequence<char, std::__1::char_traits<char> >(std::__1::basic_ostream<char, std::__1::char_traits<char> >&, char const*, unsigned long) /vectorized/llvm/bin/../include/c++/v1/ostream:722:57 #2 0x5597c4079e44 in std::__1::basic_ostream<char, std::__1::char_traits<char> >& std::__1::operator<<<char, std::__1::char_traits<char> >(std::__1::basic_ostream<char, std::__1::char_traits<char> >&, std::__1::basic_string_view<char, std::__1::char_traits<char> >) /vectorized/llvm/bin/../include/c++/v1/ostream:1057:12 #3 0x5597c602c9f3 in seastar::logger::do_log(seastar::log_level, seastar::logger::log_writer&) /v/build/v_deps_build/seastar-prefix/src/seastar/src/util/log.cc:342:15 #4 0x5597c3c4ad20 in void seastar::logger::log<char const*, int, seastar::basic_sstring<char, unsigned int, 15u, true>&>(seastar::log_level, seastar::logger::format_info, char const*&&, int&&, seastar::basic_sstring<char, unsigned int, 15u, true>&) /vectorized/include/seastar/util/log.hh:231:17 #5 0x5597c3f23c51 in void seastar::logger::trace<char const*, int, seastar::basic_sstring<char, unsigned int, 15u, true>&>(seastar::logger::format_info, char const*&&, int&&, seastar::basic_sstring<char, unsigned int, 15u, true>&) /vectorized/include/seastar/util/log.hh:385:9 #6 0x5597c3f14b95 in cloud_roles::signature_v4::sign_header(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&, std::__1::basic_string_view<char, std::__1::char_traits<char> >) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/signature.cc:382:5 #7 0x5597c3bf1dfb in cloud_roles::apply_aws_credentials::add_auth(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/apply_aws_credentials.cc:83:23 #8 0x5597c3b8f88d in cloud_roles::apply_credentials::add_auth(boost::beast::http::header<true, boost::beast::http::basic_fields<std::__1::allocator<char> > >&) const /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/apply_credentials.h:47:23 #9 0x5597c3b8c578 in test_aws_headers::test_method() /var/lib/buildkite-agent/builds/buildkite-amd64-builders-i-00e717c5e253e2891-1/redpanda/vtools/src/v/cloud_roles/tests/credential_tests.cc:50:17 ``` This change resets the ostream pointer in the wrapper destructor.
