Grafana-client

* Fixed dashboard search endpoint wrapper.
* Added support for query parameters on endpoints, also fixing `get_all_folders`.
* Added missing API wrapper for Library Elements to the Async client.
* Implemented teams read endpoints for user and actual user.

All fixes and improvements submitted by chintal. Thank you so much.

* Packaging: Do not mark package as "universal wheel" py2, py3.
Thanks, Ousret.

* Add asynchronous interface via `AsyncGrafanaClient`. Thanks, Ousret.
Changed the HTTP backend from `requests` to `niquests`.
BREAKING CHANGE: In certain conditions, you will need to adjust your code,
as it no longer propagates `requests.exceptions.Timeout` exceptions, but
uses `GrafanaTimeoutError` instead. Other than this, [Niquests] is a drop-
in replacement for [Requests] and therefore is largely compatible.
* Remove Python 3.6 support. Thanks, Ousret.
* Improve support for folders, by adding ``parent_uid`` option to relevant
endpoints, and by adding missing ``move_folder``. Thanks, grafuls.
* Service Accounts: Unlock endpoint to update service account by id.
Thanks, einar-lanfranco.
* Data Source API: Add support for Amazon Redshift and Clickhouse.
Thanks, lpfann and mysuperai.
