Added
- Added the `X-Elastic-Client-Meta` HTTP header ([PR 4](https://github.com/elastic/elastic-transport-python/pull/4))
- Added HTTP response headers to `Response` and `TransportError`
([PR 5](https://github.com/elastic/elastic-transport-python/pull/5))
- Added the `QueryParams` data structure for representing
an ordered sequence of key-value pairs for the URL query
([PR 6](https://github.com/elastic/elastic-transport-python/pull/6))
Changed
- Changed `Connection.perform_request()` to take `target` instead of
`path` and `params`. Instead `path` and `params` are created within
`Transport.perform_request()` ([PR 6](https://github.com/elastic/elastic-transport-python/pull/6))
