* [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
* feat: import/export dashboards via cli
* style: fixed lint error
* test: added test for import and export util
* test: removing import test as it is causing integrity issues
Import is a wrapper around exist functionality so we can go ahead without a test or mock the actual db operation using https://docs.python.org/3/library/unittest.mock.html
And validate the wrapper operations only.
* test: remove test data file
* test: removed usage of reserved keyword id
* Improve URLs for Chart and Dashboard ModelViews
Prior to this, the ModelView for Chart and Dashboard would be
at `/slicemodelview/list/` and `/dashboardmodelview/list/`.
Now we have cleaner URLs at `/chart/list/` and `/dashboard/list/`
