[7.17] Vega functional tests fail when run against ES 8.0

[lukeelmers]

When testing 7.17 Kibana against 8.0 Elasticsearch, we get some Vega-related failures from CI:

OSS CI Group #11 / visualize app visualize ciGroup11 vega chart in visualize app vega chart initial render should have view and control containers

In 7.17, basic Kibana functions are still expected to work when run against ES 8.0, because during an upgrade process users will upgrade ES first. So we need to identify any failures from these builds and determine if they are simply bugs in our tests, or legit issues that would be 7.17 blockers.

Talking to @flash1293, it sounds like this one might be due to #109090 needing to be backported to 7.17.

To test locally (be sure to update the config paths & string to grep for):

git checkout no-include_type_name
TEST_ES_BRANCH=8.0.0 node scripts/functional_tests_server.js --config=path/to/suite/config.ts
# in another terminal session
node scripts/functional_test_runner --config=path/to/suite/config.ts --grep="whatever"
