This PR introduces the backend changes for a tagging system for Superset, allowing dashboards, charts and queries to be tagged. It also allows searching for a given tag, and will be the basis for a new landing page (see #5327).
# Implicit tags
Dashboard, chart and (saved) queries have implicit tags related to their owners, types and favorites. For example, all objects owned by the admin have the tag `owner:1`. All charts have the tag `type:chart`. Objects favorited by the admin have the tag `favorited_by:1`.
These tags are automatically added by a migration script, and kept in sync through SQLAlchemy event listeners. They are currently not surfaced to the user, but can be searched for. For example, it's possible to search for `owner:1` in the welcome page to see all objects owned by the admin, or even search for `owner:{{ current_user_id() }}`.
* Use py3's f-strings instead of s.format(**locals())
In light of the bug reported here
https://github.com/apache/incubator-superset/issues/6347, which seems
like an odd `.format()` issue in py3, I greped and replaced all
instances of `.format(**locals())` using py3's f-strings
* lint
* fix tests
* [utils] gathering/refactoring into a "utils/" folder
Moving current utils.py into utils/core.py and moving other *util*
modules under this new "utils/" as well.
Following steps include eroding at "utils/core.py" and breaking it down
into smaller modules.
* Improve tests
* Make loading examples in scope for tests
* Remove test class attrs examples_loaded and requires_examples
* move access permissions methods to security manager
* consolidate all security methods into SupersetSecurityManager
* update security method calls
* update calls from tests
* move get_or_create_main_db to utils
* raise if supersetsecuritymanager is not extended
* rename sm to security_manager
* [sqllab] improve Hive support
* Fix "Transport not open" bug
* Getting progress bar to show
* Bump pyhive to 0.4.0
* Getting [Track Job] button to show
* Fix testzz
