In older versions of aiohttp, HEAD requests don't mark the connection as not reusable, which is why GET was used instead. But this means `indices.exists` becomes `indices.get` which can be prohibitively slow on indices with large mappings, so we want to use `HEAD` for aiohttp versions that don't have this bug. This backports the following pull requests to the 7.17 branch to make it easier for Rally to upgrade to elasticsearch-py 8.x: * elastic/elastic-transport-python#55 * elastic/elastic-transport-python#58
