After adding `emqx_rule_engine` to the `app.src` file for
`emqx_ee_schema_registry` the test suites in `emqx_ee_schema_registry`
started to fail when they where run together with
`make "lib-ee/emqx_ee_schema_registry-ct"`. However, they still worked
when executed one by one with
`SUITE=lib-ee/emqx_ee_schema_registry/test/emqx_ee_schema_registry_http_api_SUITE.erl make ct-suite`.
The failure probably happened as this changed the application start
order. As `emqx_ee_schema_registry` only requires `emqx_rule_engine` to be
loaded, `emqx_rule_engine` can be put in the included_applications list in
the emqx_ee_schema_registry.app.src file instead (this solved the issue).
Part of https://emqx.atlassian.net/browse/EMQX-9251
This ports part of the Schema Registry app from 4.x to 5.0. Here,
only support for Avro is added. Subsequent PRs will follow to add
support for other formats.
