Date histogram bwc deprecation failure

[rjernst]

Intake got a bwc test failure, which reproduces:

./gradlew ":x-pack:qa:rolling-upgrade:v7.2.0#oldClusterTestRunner" --tests "org.elasticsearch.upgrades.UpgradeClusterClientYamlTestSuiteIT.test {p0=old_cluster/40_ml_datafeed_crud/Put job and datafeed with aggs in old cluster - pre-deprecated interval}" -Dtests.seed=BF350E5616C9D3D5 -Dtests.security.manager=true -Dtests.locale=en-SC -Dtests.timezone=Asia/Nicosia -Dcompiler.java=12 -Druntime.java=11 -Dtests.rest.suite=old_cluster

The underlying failure is:

 2> java.lang.AssertionError: Failure at [old_cluster/40_ml_datafeed_crud:75]: got unexpected warning header [
        299 Elasticsearch-7.2.0-SNAPSHOT-b0a25c3 "[interval] on [date_histogram] is deprecated, use [fixed_interval] or [calendar_interval] in the future."

@polyfractal this looks related to #41906, can you take a look?

Muted in 570e8ed

I still need to update the versions after backport, and most of them are ok because they are skip: version: - 8.0.0, but this test is the other way around with skip: version: 8.0.0 - . So as soon as the 7.x backport landed it started failing.

I'd prefer to fix all those versions in one commit, so just muting this for now.

Reopening. The version issue is fixed, but the test itself is throwing an unexpected deprecation warning somewhere (either uncaught, or multiples when only one was expected). Investigating
